Correct for the size of the tabs when calculating our initial window size (#4825)
## Summary of the Pull Request

This fixes our calculation for the initial size of the window. WE weren't accounting for the height of the tabs, so the `initialRows` was consistently wrong.

## PR Checklist
* [x] Closes #2061
* [x] I work here
* [ ] Tests added/passed
* [n/a] Requires documentation to be updated

## Detailed Description of the Pull Request / Additional comments

For the tabs below the titlebar case, there's 6px (unscaled) of space that I cannot account for. I seriously have no idea where it's coming from. When we end up creating the first `TermControl` after startup, there's an inexplicable `6*scale` difference between the height of the `tabContent` and the `SwapChainPanel`'s size.

## Validation Steps Performed

Checked all six of the following cases:
* 1.0 DPI scaling, Tabs in Titlebar
* 1.25 DPI scaling, Tabs in Titlebar
* 1.0 DPI scaling, Tabs NOT in Titlebar, always show tabs
* 1.0 DPI scaling, Tabs NOT in Titlebar, DON'T always show tabs
* 1.25 DPI scaling, Tabs NOT in Titlebar, always show tabs
* 1.25 DPI scaling, Tabs NOT in Titlebar, DON'T always show tabs

Make ctrl+shift+scroll toggle acrylic on/off at extrema (#4853)
If UseAcrylic is disabled, CTRL+SHIFT+SCROLL would enable it, without
having to change the setting in profile.json manually.

1. Set "useAcrylic" to false for the any profile in profile.json
2. Open terminal window for that profile.
3. CTRL+SHIFT+MouseScroll
   Acrylic background opacity should change according to mouse scroll

Prevent tab reordering while elevated (#4874)
There's a platform limitation that causes us to crash when we rearrange
tabs. Xaml tries to send a drag visual (to wit: a screenshot) to the
drag hosting process, but that process is running at a different IL than
us.

For now, we're disabling elevated drag.

Don't let ConptyConnection be UAF (#4871)
I noticed a crash in debug builds when a connected application terminates;
we get its exit code, then we destruct, and the u16state is used after it's
destructed by us parsing the process's last words.

We should have been doing this all along.

Move dirty interface to N rectangles, not just one (#4854)
## Summary of the Pull Request
- Changes the `IRenderEngine` interface to return a vector of values instead of just a single one. Engines that want to report one still can. Engines that want to report multiple smaller ones will be able to do so going forward.

## PR Checklist

* [x] I work here.
* [x] Manually tested it still works.
* [x] Am core contributor.

## Detailed Description of the Pull Request / Additional comments
- Some of my ideas for the `DxEngine` require the ability to specify multiple smaller rectangles instead of one giant one, specifically to mitigate the case where someone refreshes just one cell in two opposite corners of the display (which currently coalesces into refreshing the entire display.)
- This is pulled out into an individual PR to make it easier to review that concept changing.

Suppress run breaking for abs. differences < 0.001 in advance (#4861)
With certain font faces at certain sizes, the advances seem to be
slightly more than the pixel grid; Cascadia Code at 13pt (though, 200%
scale) had an advance of 10.000001.

This commit makes it so that anything sub-1/100 of a cell won't make us
break up runs, because doing so results in suboptimal rendering.

Show InputPanel on focus and pointer press (#4867)
<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
I originally thought that setting `TSFInputControl::_editContext.InputPaneDisplayPolicy` to be Automatic would allow the InputPanel to show and hide automatically when `TSFInputControl` gains and loses focus. It doesn't seem to behave that way, so we'll show the InputPanel manually. 

I'll show the panel during `PointerPressedHandler` and during `GotFocusHandler`. A user will have the on-screen keyboard pop up when getting focus, but if they close the keyboard, they can simply re-tap on the terminal to bring it back up.

Reveal the taskbar when the user has the Terminal maximized or fullscreen (#4857)
## Summary of the Pull Request

When we are maximized or fullscreened, check for the presence of the taskbar in auto-hide mode. If the Terminal finds the taskbar on any side of the monitor, adjust our window rect by just a little bit, so that the taskbar can still be revealed by the user mousing over that edge.

## Detailed Description of the Pull Request / Additional comments

Note to future code archeologists:
This doesn't seem to work for fullscreen on the primary display. However, testing a bunch of other apps with fullscreen modes and an auto-hiding taskbar has shown that _none_ of them reveal the taskbar from fullscreen mode. This includes Edge, Firefox, Chrome, Sublime Text, Powerpoint - none seemed to support this. 

This does however work fine for maximized.

## Validation Steps Performed

I'm maximized and fullscreened the Terminal a lot in the last two days.

Ignore right-click copy when copy on select is enabled (#4819)
<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
Right clicking on a focused tab while Copy On Select is active currently copies any active selection. This is because `PointerReleasedHandler` doesn't check for the mouse button that was released. 
During a mouse button release, only the left mouse button release should be doing anything.

## Validation Steps Performed
These are the scenarios I've tested. They're a combination of in focus/out of focus, Copy On Select on/off, left/right click pressed and their move and release variants.

From Out of Focus:
- Left Click = Focus
- Left Click Move = Focus + Selection
- Left Click Release
  - CoS on = Copy
  - CoS off = Nothing
- Shift Left Click = Focus
- Right Click 
  - Focus 
  - CoS on = Paste
  - CoS off = Copy if Active Selection, Paste if not.
- Right Click Move = Nothing
- Right Click Release = Nothing

From In Focus
- Left Click = Selection if CoS off
- Left Click Move = Selection
- Left Click Release
  - CoS on = Copy
  - CoS off = Nothing
- Shift Left Click = Set Selection Anchor
- Right Click 
  - CoS on = Paste
  - CoS off = Copy if Active Selection, Paste if not.
- Right Click Move = Nothing
- Right Click Release = Nothing

Update the dragbar when the titlebar content size changes (#4845)
## Summary of the Pull Request

Add a `SizeChanged` handler to the titlebar content UI element. It's possible that this element's size will change after the dragbar's. When that happens, the drag bar won't send another `SizeChanged` event, because the dragbar's _size_ didn't change, only it's position.

Send TSF input buffer starting from _activeTextStart to the end of the buffer (#4836)
<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
Emoji composition was only being shown one letter at a time. This is because of the way I expected `CoreTextTextUpdatingEventArgs.Range` to be provided to TSFInputControl during composition (for Chinese/Japanese IME). Emoji IME composition gives the `StartCaretPosition` as the same as `EndCaretPosition`, unlike how for Chinese/Japanese IME, `StartCaretPosition` is usually the start of the composition and `EndCaretPosition` is the latest character in the composition. The solution is to change the `_inputBuffer.substr()` call to simply grab all of the buffer starting from `_activeTextStart`. This way I can ensure that I grab all of the "active text", instead of trusting the given `args.Range` to tell me the active text.

Abstract GetTextForClipboard() for UIA (#4578)
## Summary of the Pull Request
`GetTextForClipboard` already exists in the TextBuffer. It makes sense to use that for UIA as well. This changes the behavior or `GetText()` such that it does not remove leading/trailing whitespace anymore. That is more of an expected behavior.

## References
This also contributes to...
- #4509: UIA Box Selection
- #2447: UIA Signaling for Selection
- #1354: UIA support for Wide Glyphs
Now that the expansion occurs at before render-time, the selection anchors are an accurate representation of what is selected. We just need to move GetText to the TextBuffer. Then we can have those three issues just rely on code from the text buffer. This also means ConHost gets some of this stuff for free 😀

## Detailed Description of the Pull Request / Additional comments
- `TextBuffer::GetTextForClipboard()` --> `GetText()`
- `TextBuffer::GetText()` no longer requires GetForegroundColor/GetBackgroundColor. If either of these are not defined, we return a `TextAndColor` with only the `text` field populated.
- renamed a few parameters for copying text to the clipboard for clarity
- Updated `UiaTextRange::GetText()` to use `TextBuffer::GetText()`

## Validation Steps Performed
Manual tests for UIA using accessibility insights and Windows Terminal's copy action (w/ and w/out shift)

Added tests as well.

Polish AutomationProperties and UIA Tree Navigation (#4805)
AutomationProperties of interest in this PR include...
- Name: the name of a UI element (generally used as the main identifier
  for it)
- HelpText: an additional description for a more complex UI element
- AccessibilityView[1]
  - Raw: hide from the UIA tree. Only navigate to this if you know what
    you're doing
  - Control: a control without any content in it. Basically, a point at
    which the user can make a decision as to how to navigate the tree or
    invoke an action.
  - Content: a control that also has content to present to the user.

I set a few more AutomationProperties throughout Windows Terminal...
- MinMaxClose Control: hidden (we can/should rely on the true buttons
  that we are hiding)
- SplitButton: Name and Help text (currently ignored due to #4804, but
  having it in the resource file won't cause any problems)

Tunnel F7 keypresses directly into special handlers in TermControl (#4807)
The Xaml input stack doesn't allow an application to suppress the "caret
browsing" dialog experience triggered when you press F7.

The official recommendation from the Xaml team is to catch F7 before we
hand it off.

This commit introduces a special F7 handler and an ad-hoc implementation of event bubbling.
Runtime classes implementing a custom IF7Listener interface are
considered during a modified focus parent walk to determine who can
handle F7 specifically.

If the recipient control handles F7, we suppress the message completely.

This event bubbler has some minor issues -- the search box will not be
able to receive F7 because its parent control implements the handler.
Since search is already mostly a text box, it doesn't _need_ special
caret browsing functionality as far as I can tell.

TermControl implements its OnF7Pressed handler by synthesizing a
keybindings event and an event to feed into Terminal Core directly.

It's not possible to create a synthetic KeyPressRoutedEvent; if it were,
I would have just popped one into the traditional input queue. :)

Fixes #638.

Improve Word Navigation/Selection Performance (#4797)
## Summary of the Pull Request
1) Improves the performance of word-recognition operations such as word
   navigation in UIA and selection.

2) Fixes a bug where attempting to find the next word in UIA, when none

## Detailed Description of the Pull Request / Additional comments
- The concept of a delimiter class got moved to the CharRow.
- The buffer iterator used to save a lot more information than we needed
- I missed updating a tracing function after making GetSelection return
  one text range. That is fixed now.

Make Korean IME input more consistent (#4796)
## Summary of the Pull Request
Korean IME was not working correctly due to way we were clearing the input buffer inside of `TSFInputControl`. We wanted to clear our input buffer and tell TSF to clear its input buffer as well when we receive a `CompositionCompleted` event. This works fine in some IME languages such as Chinese and Japanese. However, Korean IME composes characters differently in such a way where we can't tell TSF to clear their buffer during a `CompositionCompleted` event because it would clear the character that triggered the `CompositionCompleted` event in the first place.

The solution in this PR is to keep our `_inputBuffer` intact until the user presses <kbd>Enter</kbd> or <kbd>Esc</kbd>, in which case we clear our buffer and the TSF buffer. I've chosen these two keys because it seems to make sense to clear the buffer after text is sent to the terminal with <kbd>Enter</kbd>, and <kbd>Esc</kbd> usually means to cancel a current composition anyway.

This means we need to keep track of our last known "Composition Start Point", which is represented by `_activeTextStart`. Whenever we complete a composition, we'll send the portion of the input buffer between `_activeTextStart` and the end of the input buffer to the terminal. Then, we'll update `_activeTextStart` to be the end of the input buffer so that the next time we send text to the terminal, we'll only send the portion of our buffer that's "active".

AzCon: improve input, usability, reliability (4 commits) (#4756)
* Azure: rewrite user input handler

This commit replaces the AzureConnection's input handler with one that
acts more like "getline()". Instead of the Read thread setting a state
and WriteInput filling in the right member variable, the reader blocks
on the user's input and receives it in an optional<string>.

This moves the input number parsing and error case handling closer to
the point where those inputs are used, as opposed to where they're
collected.

It also switches our input to be "line-based", which is a huge boon for
typing tenant numbers >9. This fixes #3233. A simple line editor
(supporting only backspace and CR) is included.

It also enables echo on user input, and prints it in a nice pretty green
color.

It also enables input queueing: if the user types anything before the
connection is established, it'll be sent once it is.

Fixes #3233.

* Azure: display the user's options and additional information in color

This commit colorizes parts of the AzCon's strings that include "user
options" -- things the user can type -- in yellow. This is to help with
accessibility.

The implementation here is based on a discussion with the team.
Alternative options for coloration were investigated, such as:

* Embedding escape sequences in the resource file.
  This would have been confusing for translators.
  The RESW file format doesn't support &#x1B; escapes, so we would need

Do what the comment actually says and only insert 0s if we were given more text than the column value we were also given. (#4781)
## Summary of the Pull Request
Adjusts column padding code in `CustomTextLayout` to only pad out for surrogate pairs, not anything that reports two columns.

## References
- See also #4747

## PR Checklist
* [x] Closes #4780
* [x] I work here.
* [x] Manual tests.
* [x] No doc, this fixes code to match comment. Oops.
* [x] Am core contributor. Also discussed with @leonMSFT. 

## Detailed Description of the Pull Request / Additional comments
For surrogate pairs like high Unicode emoji, we receive two wchar_ts but only one column count (which is usually 2 because emoji are usually inscribed in the full-width squares.) To compensate for this, I added in a little padding function at the top of the `CustomTextLayout` construction that adds a column of 0 aligned with the second half of a surrogate pair so the text-to-glyph mapping lines up correctly.

Unfortunately, I made a mistake while either responding to PR feedback in #4747 or in the first place and I made it pad out extra 0 columns based on the FIRST column count, not based on whether or not there is a trailing surrogate pair. The correct thing to do is to pad it out based on the LENGTH of text associated with the given column count. This means that full width characters which can be represented in one wchar_t, like those coming from the IME in most cases (U+5C41 for example) will have a column count of 2. This is perfectly correct for mapping text-to-glyphs and doesn't need a 0 added after it. A house emoji (U+1F3E0) comes in as two wchar_ts (0xD83C 0xDFE0) with the column count of 2. To ensure that the arrays are aligned, the 2 matches up with the 0xD83C but the 0xDFE0 needs a 0 on it so it will be skipped over. (Don't worry, because it's a surrogate, it's naturally consumed correctly by the glyph mapper.)

The effect was that every OTHER character inserted by the IME was scaled to 0 size (as an advance of 0 was expected for 0 columns).
The fix restores it so those characters don't have an associated count and aren't scaled.

## Validation Steps Performed
- Opened it up
- Put in the house emoji like #4747 (U+1f3e0)
- Put in some characters with simplified Chinese IME (fixed now)
- Put in the utf83.txt sample text used in #4747

## Detailed Description of the Pull Request / Additional comments
- The `_CorrectGlyphRun` function now walks through and uses the
  `_glyphClusters` map to determine the text span and glyph span for each
  cluster so it can be considered as a single unit for scaling.
- The total number of columns expected across the entire cluster
  text/glyph unit is considered for the available spacing for drawing
- The total glyph advances are summed to see how much space they will
  take
- If more space than necessary to draw, all glyphs in the cluster are
  offset into the center and the extra space is padded onto the advance of
  the last glyph in the range.
- If less space than necessary to draw, the entire cluster is marked for
  shrinking as a single unit by providing the initial text index and
  length (that is back-mapped out of the glyph run) up to the parent
  function so it can use the `_SetCurrentRun` and `_SplitCurrentRun`
  existing functions (which operate on text) to split the run into pieces
  and only scale the one glyph cluster, not things next to it as well.
- The scale factor chosen for shrinking is now based on the proportion
  of the advances instead of going through some font math wizardry
- The parent that calls the run splitting functions now checks to not
  attempt to split off text after the cluster if it's already at the end.
  This was @DHowett-MSFT's crash.
- The split run function has been corrected to fix the `glyphStart`
  position of the back half (it failed to `+=` instead of `=` which
  resulted in duplicated text, sometimes).
- Surrogate pair emoji were not allocating an appropriate number of
  `_textClusterColumns`. The constructor has been updated such that the
  trailing half of surrogate pairs gets a 0 column width (as the lead is
  marked appropriately by the `GetColumns()` function). This was the
  exception thrown.
- The `_glyphScaleCorrections` array stored up over the calls to
  `_CorrectGlyphRun` now uses a struct `ScaleCorrection` as we're up to 3
  values.
- The `ScaleCorrection` values are named to clearly indicate they're in
  relation to the original text span, not the glyph spans.
- The values that are used to construct `ScaleCorrection`s within
  `_CorrectGlyphRun` have been double checked and corrected to not
  accidentally use glyph index/counts when text index/counts are what's
  required.

## Validation Steps Performed
- Tested the utf82.txt file from one of the linked bugs. Looked
  specifically at Burmese through Thai to ensure restoration (for the most

Move rect expansion to textbuffer; refactor selection code (#4560)
- When performing chunk selection, the expansion now occurs at the time
  of the selection, not the rendering of the selection
- `GetSelectionRects()` was moved to the `TextBuffer` and is now shared
  between ConHost and Windows Terminal
- Some of the selection variables were renamed for clarity
- Selection COORDs are now in the Text Buffer coordinate space
- Fixes an issue with Shift+Click after performing a Multi-Click
  Selection

## References
This also contributes to...
- #4509: UIA Box Selection
- #2447: UIA Signaling for Selection
- #1354: UIA support for Wide Glyphs

Now that the expansion occurs at before render-time, the selection
anchors are an accurate representation of what is selected. We just need
to move `GetText` to the `TextBuffer`. Then we can have those three
issues just rely on code from the text buffer. This also means ConHost
gets some of this stuff for free 😀

### TextBuffer
- `GetTextRects` is the abstracted form of `GetSelectionRects`
- `_ExpandTextRow` is still needed to handle wide glyphs properly

### Terminal
- Rename...
    - `_boxSelection` --> `_blockSelection` for consistency with ConHost
    - `_selectionAnchor` --> `_selectionStart` for consistency with UIA
    - `_endSelectionPosition` --> `_selectionEnd` for consistency with
      UIA
- Selection anchors are in Text Buffer coordinates now
- Really rely on `SetSelectionEnd` to accomplish appropriate chunk
  selection and shift+click actions

## Validation Steps Performed
- Shift+Click
- Multi-Click --> Shift+Click
- Chunk Selection at...
    - top of buffer
    - bottom of buffer
    - random region in scrollback

Fix RenderThread's notify mechanism (#4698)
## Summary of the Pull Request

Fix a bug where the `Renderer::PaintFrame` method:
1. is not called until the next `RenderThread::NotifyThread` call but needs to be called because there the terminal was updated (theoretical bug)
2. is called twice but needs to be called only once (verified bug)

The bug was introduced by #3511.

## Detailed Description of the Pull Request / Additional comments

### Before

#### First bug

In the original code, `_fNextFrameRequested` is set to `true` in render thread because `std::atomic_flag::test_and_set` is called.

This is wrong because it means that the render thread will render the terminal again even if there is no change after the last render.

I think the the goal was to load the boolean value for `_fNextFrameRequested` to check whether the thread should sleep or not.

The problem is that there is no method on `std::atomic_flag` to load its boolean value. I guess what happened was that the "solution" that was found was to use `std::atomic_flag::test_and_set`, followed by `std::atomic_flag::clear` if the value was `false` originally (if `std::atomic_flag::test_and_set` returned `false`) to restore the original value. I guess that this was believed to be equivalent to just a simple load, without doing any change to the value because it restores it at the end.

But it's not: this is dangerous because if the value is changed to `true` between the call to `std::atomic_flag::test_and_set` and the call to `std::atomic_flag::clear`, then the value ends up being `false` at the end which is wrong because we don't want to change it! And if that value ends up being `false`, it means that we miss a render because we will wait on `_hEvent` during the next iteration on the render thread.

Well actually, here, this not even a problem because when that code is ran, `_fPainting` is `false` which means that the other thread that modifies the `_fNextFrameRequested` value through `RenderThread::NotifyPaint` will not actually modify `_fNextFrameRequested` but rather call `SetEvent` (see the method's body).

But wait! There is a problem there too! `std::atomic_flag::test_and_set` is called for `_fPainting` which sets its value to `true`. It was probably unintended. So actually, the next call to `RenderThread::NotifyPaint` _will_ end up modifying `_fNextFrameRequested` which means that the data race I was talking about _might_ happen!

#### Second bug

Let's go back a little bit in my explanation. I was talking about the fact that:

> I guess what happened was that the "solution" that was found was to use `std::atomic_flag::test_and_set`, followed by `std::atomic_flag::clear` if the value was `false` originally (if `std::atomic_flag::test_and_set` returned `false`) to restore the original value.

The problem is that the reverse was done in the implementation: `std::atomic_flag::clear` is called if the value was _`true`_ originally!

So at this point, if the value of `_fNextFrameRequested` was `false`, then `std::atomic_flag::test_and_set` sets its is set to `true` and returns `false`. So for the next iteration, `_fNextFrameRequested` is `true` and the render thread will re-render but that was not needed.

### After

I used `std::atomic<bool>` instead of `std::atomic_flag` for `_fNextFrameRequested` and the other atomic field because it has a `load` and a `store` method so we can actually load the value without changing it.

I also replaced `_fPainting` by `_fWaiting`, which is basically the opposite of `_fPainting` but stays `true` for a little shorter than `_fPainting` would stay `false`. Indeed, I think that it makes more sense to directly wrap/scope _just_ the call to `WaitForSingleObject` by setting my atomic variable to `true` _just_ before and to `false` _just_ after because:
* It makes more sense while you're reading the code: it's easier IMO to understand what the purpose of `_fWaiting` is (that is, to call `SetEvent` from `RenderThread::NotifyPaint` if it's `true`).
* It's probably a tiny bit better for performance because it will become `true` for a little shorter which means less calls to `SetEvent`.

#### Warning

I don't really understand [std::memory_order](https://en.cppreference.com/w/cpp/atomic/memory_order)s.

So I used the default one (`std::memory_order_seq_cst`) which is the safest.

I believe that if no read or write are reordered in the two threads (`RenderThread::NotifyPaint` and `RenderThread::_ThreadProc`), then the code I wrote will behave correctly.

I think that `std::memory_order_seq_cst` enforces that so it should be fine, but I'm not sure.

## Validation Steps Performed

**I tried to reproduce the second bug that I described in the first section of this PR.**

I put a breakpoint on `RenderThread::NotifyPaint` and on `Renderer::PaintFrame`. Initially they are disabled. Then I ran the terminal in Release mode, waited a bit for the prompt to display and the cursor to start blinking. Then I enabled the breakpoints.

### Before

Each `RenderThread::NotifyPaint` is followed by 2 `Renderer::PaintFrame` calls.  

### After

Each `RenderThread::NotifyPaint` is followed by 1 `Renderer::PaintFrame` call. ✔️

Make Conpty emit wrapped lines as actually wrapped lines (#4415)
## Summary of the Pull Request

Changes how conpty emits text to preserve line-wrap state, and additionally adds rudimentary support to the Windows Terminal for wrapped lines.

## References

* Does _not_ fix (!) #3088, but that might be lower down in conhost. This makes wt behave like conhost, so at least there's that
* Still needs a proper deferred EOL wrap implementation in #780, which is left as a todo
* #4200 is the mega bucket with all this work
* MSFT:16485846 was the first attempt at this task, which caused the regression MSFT:18123777 so we backed it out.

## PR Checklist
* [x] Closes #405
* [x] Closes #3367 
* [x] I work here
* [x] Tests added/passed
* [n/a] Requires documentation to be updated

## Detailed Description of the Pull Request / Additional comments

I started with the following implementation:
When conpty is about to write the last column, note that we wrapped this line here. If the next character the vt renderer is told to paint get is supposed to be at the start of the following line, then we know that the previous line had wrapped, so we _won't_ emit the usual `\r\n` here, and we'll just continue emitting text.

However, this isn't _exactly_ right - if someone fills the row _exactly_ with text, the information that's available to the vt renderer isn't enough to know for sure if this line broke or not. It is possible for the client to write a full line of text, with a `\n` at the end, to manually break the line. So, I had to also add the `lineWrapped` param to the `IRenderEngine` interface, which is about half the files in this changelist.

## Validation Steps Performed
* Ran tests
* Checked how the Windows Terminal behaves with these changes
* Made sure that conhost/inception and gnome-terminal both act as you'd expect with wrapped lines from conpty

Don't split surrogate pairs when breaking runs for scaling. Affects emoji rendering. #4704 (#4731)
## Summary of the Pull Request
- Surrogate pairs are being split in half with the run splitting check.

## References
- Related to #4708 but not going to fix it.

## PR Checklist
* [x] Closes #4704
* [x] I work here.
* [x] I am a core contributor.

## Detailed Description of the Pull Request / Additional comments
- The adjustment of the run heights in the correction function reports back a text index and a scaling factor. However, I didn't remember at the time that the text is being stored as UTF-16. So the index given can be pointing to the high surrogate of a pair. Thus adding 1 to split "after" the text character, then backing up by 1 isn't valid in if the index given was for a high surrogate.

The quick fix is to advance by two if it's a high surrogate and one otherwise.

## Validation Steps Performed
- Used the sample code from #4704 to print the house emoji in various situations into the buffer.

Allow IME input in Search Box (#4723)
## Summary of the Pull Request
Currently, when the user attempts to type using IME while the Search Box is focused, the input goes to the terminal instead. This is due to the fact that the `TSFInputControl` assumes it's in control whenever TermControl gets focus. So, it'll intercept IME input before the Search Box receives it. We simply need to modify `TermControl::GotFocus` to check if the SearchBox has focus. If it does, `TSFInputControl::NotifyFocusEnter` shouldn't be called.

As a small side fix, I've also disabled the terminal cursor blinking when the Search Box has focus.

Thinking a little further, if we have more features in the future that behave like search box (i.e. advanced tab switcher, or any other XAML controls that pop up) and require text input, we might need to create a sort of "AnyOtherTextControlInFocus" function to see if TSFInputControl should receive focus or not.

Search works as expected with IME. Composition picker appears underneath Search Box when typing IME in the Search Box. Clicking outside of the Search Box still returns control to TSFInputControl/TermControl.

Display Emojis, Kaomojis, and symbols while in IME mode (#4688)
## Summary of the Pull Request
Currently, while in IME mode, selections with the Emoji/Kaomoji/Symbol Picker (which is brought up with <kbd>win+.</kbd>) are not displayed until the user starts a new composition. This is due to the fact that we hide the TextBlock when we receive a CompositionCompleted event, and we only show the TextBlock when we receive a CompositionStarted event. Input from the picker does not count as a composition, so we were never showing the text box, even if the symbols were thrown into the inputBuffer. In addition, we weren't receiving CompositionStarted events when we expected to.

We should be showing the TextBlock when we receive _any_ text, so we should make the TextBlock visible inside of `TextUpdatingHandler`. Furthermore, some really helpful discussion in #3745 around wrapping the `NotifyTextChanged` call with a `NotifyFocusLeave` and a `NotifyFocusEnter` allowed the control to much more consistently determine when a CompositionStarted and a CompositionEnded.

I've also went around and replaced casts with saturating casts, and have removed the line that sets the `textBlock.Width()` so that it would automatically set its width. This resolves the issue where while composing a sentence, the textBlock would be too small to contain all the text, so it would be cut off, but the composition is still valid and still able to continue.

Add support for cleartype text antialiasing (#4711)
## Summary of the Pull Request

I needed to do something to keep sane so today I day of learned about antialiasing. This PR adds the ability to specify the `"antialiasingMode"` as a setting.
* "antialiasingMode": "grayscale": the current behavior, `D2D1_TEXT_ANTIALIAS_MODE_GRAYSCALE`
* "antialiasingMode": "cleartype": use `D2D1_TEXT_ANTIALIAS_MODE_CLEARTYPE` instead

hook up UIA tree to WPF control (#4548)
This PR hooks up the existing UIA implementation to the WPF control. Some existing code that was specific to the UWP terminal control could be shared so that has been refactored to a common location as well.

## Validation Steps Performed
WPF control was brought up in UISpy and the UIA tree was verified. NVDA was then used to check that screen readers were operating properly.

make sure caching of partials still works if the string consists of a single lead byte only (GH#4673) (#4685)
## Summary of the Pull Request
Fixes a flaw that happened if `til::u8u16` received a single lead byte.

## PR Checklist
* [x] Closes #4673 
* [x] Tests added/passed

## Detailed Description of the Pull Request / Additional comments
The loop for caching partials didn't run and thus, the lead byte was
converted to U+FFFD. That's because the loop starts with `sequenceLen`
initialized with 1. And if the string has a length of 1 the initial
condition is `1<1` which is evaluated to `false` and the body of the
loop was never executed.

## Validation Steps Performed
1) updated the code of the state class and tested manually that `printf
   "\xE2"; printf "\x98\xBA\n"` prints a U+263A character
2) updated the unit tests to make sure that still up to 3 partials are
   cached
3) updated the unit tests to make sure caching also works if the string
   consists of a lead byte only
4) tested manually that #4086 is still resolved

Clip text to within the row we expect (#4671)
## Summary of the Pull Request
Adjusts `DrawGlyphRun` method inside DirectX renderer to restrict text
to be clipped within the boundaries of the row.

## PR Checklist
* [x] Closes #1703
* [x] I work here.
* [x] No tests.
* [x] No docs.
* [x] I am core contributor.

## Detailed Description of the Pull Request / Additional comments
For whatever reason, some of these shade glyphs near U+2591 tend to
extend way above the height of where we expect they should. This didn't
look like a problem in conhost because it clipped every draw inside the
bounds. This therefore applies the same clip logic as people don't
really expect text to pour out of the box.

It could, theoretically, get us into trouble later should someone
attempt zalgo text. But doing zalgo text is more of a silliness that
varies in behavior across rendering platforms anyway.

## Validation Steps Performed
- Ran the old conhost GDI renderer and observed
- Ran the new Terminal DX renderer and observed
- Made the code change
- Observed that the height and approximate display characteristics of
  the U+2591 shade and neighboring characters now matches with the conhost
  GDI style to stay within its lane.

Restrict DX run height adjustment to only relevant glyph AND Correct PTY rendering on trailing half of fullwidth glyphs (#4668)
## Summary of the Pull Request
- Height adjustment of a glyph is now restricted to itself in the DX
  renderer instead of applying to the entire run
- ConPTY compensates for drawing the right half of a fullwidth
  character. The entire render base has this behavior restored now as
  well.

## PR Checklist
* [x] Closes #2191
* [x] I work here
* [x] Tests added/passed
* [x] No doc
* [x] Am core contributor.

## Detailed Description of the Pull Request / Additional comments
Two issues:
1. On the DirectX renderer side, when confronted with shrinking a glyph,
   the correction code would apply the shrunken size to the entire run, not
   just the potentially individual glyph that needed to be reduced in size.
   Unfortunately while adjusting the horizontal X width can be done for
   each glyph in a run, the vertical Y height has to be adjusted for an
   entire run. So the solution here was to split the individual glyph
   needing shrinking out of the run into its own run so it can be shrunk.
2. On the ConPTY side, there was a long standing TODO that was never
   completed to deal with a request to draw only the right half of a
   two-column character. This meant that when encountering a request for
   the right half only, we would transmit the entire full character to be
   drawn, left and right halves, struck over the right half position. Now
   we correct the cursor back a position (if space) and draw it out so the
   right half is struck over where we believe the right half should be (and
   the left half is updated as well as a consequence, which should be OK.)

The reason this happens right now is because despite VIM only updating
two cells in the buffer, the differential drawing calculation in the
ConPTY is very simplistic and intersects only rectangles. This means
from the top left most character drawn down to the row/col cursor count
indicator in vim's modeline are redrawn with each character typed. This
catches the line below the edited line in the typing and refreshes it.
But incorrectly.

We need to address making ConPTY smarter about what it draws
incrementally as it's clearly way too chatty. But I plan to do that with
some of the structures I will be creating to solve #778.

## Validation Steps Performed
- Ran the scenario listed in #2191 in vim in the Terminal
- Added unit tests similar to examples given around glyph/text mapping
  in runs from Microsoft community page

UIA: Fix GetVisibleRanges() and add Tracing (#4495)
## Summary of the Pull Request
Debugging our custom UIA providers has been a painful experience because outputting content to VS may result in UIA Clients getting impatient and giving up on extracting data.

Adding tracing allows us to debug these providers without getting in the way of reproducing a bug. This will help immensely with developing accessibility features on Windows Terminal and Console.

This pull request additionally contains payload from #4526:
* Make GetVisibleRanges() return one range (and add tracing for it).
`ScreenInfoUiaProvider::GetVisibleRanges()` used to return one range per line of visible text. The documentation for this function says that we should return one per contiguous span of text. Since all of the text in the TermControl will always be contiguous (at least by our standards), we should only ever be returning one range.

## PR Checklist
* [x] Closes #1914. Closes #4507.
* [x] CLA signed

## Detailed Description of the Pull Request / Additional comments
`UiaTracing` is a singleton class that is in charge of registration for trace logging. `TextRange` is used to trace `UiaTextRange`, whereas `TextProvider` is used to trace `ScreenInfoUiaProviderBase`.

`_getValue()` is overloaded to transform complex objects and enums into a string for logging.

`_getTextValue()` had to be added to be able to trace the text a UiaTextRange included. This makes following UiaTextRanges much simpler.

## Validation Steps Performed
Performed a few operations when under NVDA/Narrator and manually checked the results.

We used to return multiple text ranges to represent one selection. We only support one selection at a time, so we should only return one range.

Fix duplicate copyOnSelect when clicking on an unfocused terminal (#4596)
## Summary of the Pull Request
Currently, clicking on an unfocused terminal with a selection active will trigger `copyOnSelect`. This is because the check for `copyOnSelect` and copying to the clipboard is bound to when the Pointer is released. This works fine for when a user performs a click-drag selection, but it inadvertently also triggers when the user performs a single click on an unfocused terminal. We expect `copyOnSelect` to trigger only on the first time a selection is completed. 

This PR will allow the user to single click on an unfocused terminal that has a selection active without triggering a copyOnSelect. It also ensures that any click-drag selection, whether it's on an unfocused or focused terminal, will trigger copyOnSelect.

James 8392d6b647 Fix touchpad and touchscreen scrolling (#4554)
Fixed inconsistent scrolling when using both touchscreen and precision
touchpad.

Scrolling jumpiness is caused by rounding errors. Instead of retrieving
the current scrolling value from `GetScrollOffset`, which is already
rounded in `int`, let the scrolling operation to operate on
`_scrollBar`'s `Value` directly (which uses `double`) in
`TermControl.cpp`.

TermControl now also respects WHEEL_DELTA, which it was previously
ignoring, to determine how many scroll wheel detents were used.

Testing scrolling on the following scenario manually:

- nonscrollable terminal (e.g. the window is large enough to contain the
  current buffer).
- scrolling to the topmost and bottom-most.
- scrolling TUI apps such as `nano` and `more` in WSL.
- after clearing the terminal, both in cmd and WSL.

... has the same behavior between using touchscreen or precision trackpad
and regular mouse wheel.

Fix click-drag selection on an unfocused Terminal (#4506)
## Summary of the Pull Request
This PR tries to address some of the weird interactions with pointer pressed events when the Terminal isn't in focus. Here's the four things that have changed as part of this PR;

1. This PR will allow the user to be able to make a selection with a click-drag without having to first perform a single click on a tab/pane to bring it to focus. 
2. Another weird bug that's fixed in this PR is where trying to make a selection on an unfocused tab when it already has a selection active will simply extend the existing selection instead of making a new one.
3. Not related to the issue that his PR closes: a right click will now focus the tab/pane.

I've made sure that we still have the existing functionality where a single click on an unfocused tab/pane does not make a single-cell selection and just focuses the tab/pane.

When patching profiles in, copy the user's indentation (#4555)
This will attempt to match the style of the user's JSON.

Caveats:
1. If the user has no profiles, it'll explode. This isn't new.
2. If the user's indentation style if `{profile}, {profile}, {profile}` (that is: no indentation), you'll get this:

```
{profile}, {profile}, {profile},
 {
     new profile content
 }
```

There may be something better we can do by copying their newline (or lack thereof) and using it in our generator or detecting the indentation of their members as well.
That's an exercise for later.

- "Microsoft.Windows.Terminal.Connection" {e912fe7b-eeb6-52a5-c628-abe388e5f792}
- "ConPtyConnected" event
- "SessionGuid" value = WT_SESSION 
- "Client" value = Name of EXE
2. Is Acrylic used on a tab? And with what opacity? (Do people really want acrylic? Should it be default? What opacity is most pleasing in our context?)
- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}
- "TabInformation" event
- "EventVer" value is now 1u
- "UseAcrylic" value is now TRUE/FALSE on the setting choice
- "TintOpacity" value is now Float on the setting choice
3. What font are people choosing? (Do people move away from Cascadia Code? Which ones are the most popular for us to validate when updating the renderer?)
- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}
- "TabInformation" event
- "FontFace" value is now string font from settings
4. What keybindings do people choose to customize (Add or Remove)? (Are there extremely common keys that folks bind or unbind that we should have adjusted by default in a fresh install?)
- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}
- "CustomKeybindings" event
- "Keybindings" value is the entire JSON segment that describes the user keybindings from `settings.json`.
5. Do people change their default profile from the PowerShell one we set? If so, to what? (Should we not set PowerShell as the default? Should we adjust the ranking of our dynamic generators to favor the most popular ones to bubble to the top?)
- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}
- "CustomDefaultProfile" event
- "DefaultProfile" value is the GUID of the chosen profile

Fix the crash when closing Terminal containing multiple tabs. (#4538)
The Terminal would crash when closing it when there are multiple tabs
open. This was due to `TerminalPage` attempting to select a nonexistent
tab.

The block of code that was removed was causing issues when trying to
close all tabs at once. The way we close all our tabs in
`_CloseAllTabs()` was by repeatedly calling
`_RemoveTabViewItemByIndex(0)` until `_tabs.Size() == 0`. The problem
was that `_RemoveTabViewItemByIndex` would eventually call a coroutine
to set the next tab as the `SelectedItem` after removing a tab. The
coroutine would then pass control back to `_CloseAllTabs()` to finish
its loop, and by the time the coroutine resumes control, `_tabs` and
`TabView().TabItems()` would both be empty and it would crash attempting
to focus a tab.

Luckily, the functionality that this block of code provided is really no
longer needed . This code was used to focus on the next tab after
closing a  tab. This might have been written way back when TabView
didn't have this functionality built in. It seems now that after
removing a `TabItem` from the `TabView`, the `SelectedItem` of the
TabView automatically updates, making this block of code unnecessary.

## Validation Steps Performed
Did a lot of multiple tab open and closings and closing the window after
opening a ton of tabs. No crashes seem to occur anymore!
Test cases still pass.

uia: add support for scrolling the viewport (#4525)
The UIA Provider now scrolls the viewport when necessary. This just fills in the missing virtual function in Terminal to have the same behavior as what it does in ConHost.

* [X] Closes #2361 
* [X] CLA signed.

`ChangeViewport` is now a virtual function at the `ScreenInfoUiaProvider` layer to have access to the TermControl.

In ConHost, we pass this call up to the WindowUiaProvider layer. In Terminal, we don't need to do that because the concept of updating the viewport is handled at the TermControl layer. So we just call that function and _voila_!

Move cursor in conpty correctly after a backspace when we've delayed an EOL wrap (#4403)
## Summary of the Pull Request

This is a fix that technically was caused by #357, though we didn't have the Terminal at the time, so I only fixed conhost then. When a client app prints the very last column in the buffer, the cursor is often not _actually_ moved to the next row quite yet. The cursor usually just "floats" on the last character of the row, until something happens. This could be a printable character, which will print it on the next line, or a newline, which will move the cursor to the next line manually, or it could be a backspace, which might take the cursor back a character. 

Conhost and gnome-terminal behave slightly differently here, and wt behaves differently all together. Heck, conhost behaves differently depending on what output mode you're in. 

The scenario in question is typing a full row of text, then hitting backspace to erase the last char of the row.

What we were emitting before in this case was definitely wrong - we'd emit a space at that last row, but then not increment our internal tracker of where the cursor is, so the cursor in conpty and the terminal would be misaligned. The easy fix for this is to make sure to always update the `_lastText` member appropriately. This is the `RightExclusive` change.

The second part of this change is to not be so tricksy immediately following a "delayed eol wrap". When we have just printed the last char like that, always use the VT sequence CUP the next time the cursor moves. Depending on the terminal emulator and it's flags, performing a BS in this state might not bring the cursor to the correct position.

In UIA Providers, update the concept of the size of the text buffer to just go down to the virtual bottom. This significantly increases performance to the point that it can even be used in the Debug build.

## PR Checklist
* [x] Closes #4485 
* [x] CLA signed.

## Detailed Description of the Pull Request / Additional comments
We already actually have this concept exposed to us via the IUiaData. So we're just leveraging that and putting it in a helper function `_getBufferSize()`.

## Validation Steps Performed
Tested word nav on Narrator (previously hung). Now it works on the Debug build. Previously, using the release build was necessary to be able to test this feature.

## Detailed Description of the Pull Request / Additional comments

There are two ways scroll can happen:
- the user scrolls using the scroll bar and the `Terminal` is notified
- the `Terminal` changed the viewport and the scroll bar is updated to reflect the change

The code to notify the `Terminal` that the user scrolled is in the event handler for when the scroll bar's value changes. However this poses a problem because it means that when the `Terminal` changes the viewport, the scroll bar is updated so it would then also notify the `Terminal` that the scroll changed. But it already knows because it's coming from itself!

To fix this, the `TermControl` class had a member called `_lastScrollOffset` that would be set when the `Terminal` decides to change the viewport so that the event handler for the scroll bar could check the new scroll value against `_lastScrollOffset` and if it matches, then everything is fine and there is nothing to update.

This is what happens when the `Terminal` changes the viewport:
1. set `_lastScrollOffset`
2. dispatch job on the UI thread: update the scrollbar which is going to call the event handler which is going to check for `_lastScrollOffset` and clear it

There are two bugs introduced by this approach:
1. (I am not sure about this.) The dispatcher appears to store jobs in a LIFO stack so it sometimes reorders the "update the scrollbar" jobs when there are too many. When I run `1..10000` on PowerShell, then I get this from the event handler (format: `_lastScrollOffset newValue`):
    ```
    8988 8988
    8989 8989
    8990 8990
    8992 8991
    8993 8992
    ...
    9001 8997
    9001 8998
    9001 8999
    9001 9000
    9001 9001
    9001 8985
    9001 8968
    9001 8953
    ...
    9001 7242
    9001 7226
    9001 7210
    ```
    This causes the following issues:
    1. `_lastScrollOffset` wouldn't be reset because it wouldn't be equal to the current scroll bar value (see example above) so the next scrolls wouldn't do anything as the event handler would still be waiting for an event with the good scroll bar value which would never happen because it happened earlier
    2. the `TermControl` would notify the `Terminal` about its own scroll
2. If the `Terminal` didn't actually changed its viewport but still called the `TermControl::_TerminalScrollPositionChanged` method, then it would set the `_lastScrollOffset` member as usual but the scroll bar value change event handler would not be called because it is only called when the value actually changes so the `_lastScrollOffset` member wouldn't be cleared and subsequent scroll bar value change events would be ignored because again the event handler would still be waiting for an event with the good scroll bar value which would never happen. This is actually the reason for #1494: when the window is resized, the `Terminal` will call `TermControl::_TerminalScrollPositionChanged` even if the scroll position didn't actually change (444de5b166/src/cascadia/TerminalCore/Terminal.cpp (L183)). Maybe this should also be fixed in another PR?

I replaced `_lastScrollOffset` by a flag `_isTerminalInitiatedScroll`. I set the flag just before and unset it just after the terminal changes the scrollbar on the UI thread to eliminate the race conditions and the bug when the scroll bar's value doesn't actually change.

Other changes:
- I also fixed a potential bug where if the user scrolls just after the terminal updates the viewport, it would en up ignoring the user scroll. To do this, when the user scrolls, I cancel any update with `_willUpdateScrollBarToMatchViewport`.
- I also removed the original `ScrollViewport` method because it was not used anywhere and I think it can potentially create confusion (and therefore bugs) because this method updates the viewport but not the scroll bar unlike `KeyboardScrollViewport` which functions as you would expect. I then renamed `KeyboardScrollViewport` into `ScrollViewport`. So, now, there is only one method to scroll the viewport from the `TermControl`. Please, tell me if this shouldn't be in this PR.
- I also removed `_terminal->UserScrollViewport(viewTop);` in the `KeyboardScrollViewport` method because it will be updated later anyways in the scroll bar's value change event handler because of the `_scrollBar.Value(viewTop);`.

<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed

I tested manually by doing this:
- For bug 1:
    1. Start the terminal
    2. Run the `1..30000` command in PowerShell and wait for it to end (maybe more if you have a fast  computer?)
    3. Hold left click on the scrollbar slider and start moving it
- For bug 2:
    1. Start the terminal
    2. Run the `1..100` command in PowerShell and wait for it to end
    3. Resize the window horizontally
    4. Hold left click on the scrollbar slider and start moving it

Without this patch, the viewport doesn't update.
With the patch, the viewport updates correctly.

Passthrough CSI 3 J in Conpty (#4433)
## Summary of the Pull Request

Conpty doesn't need `CSI 3 J`, it doesn't have a scrollback. The terminal that's connected should use that. This makes conpty pass it through, like other sequences that conpty has no need for.

Initialize Windows Terminal in STA (#4505)
This fixes a crash caused by Narrator starting *before* terminal.

Fixes #2907.

For context,

```
// We must initialize the main thread as a single-threaded apartment before
// constructing any Xaml objects. Failing to do so will cause some issues
// in accessibility somewhere down the line when a UIAutomation object will
// be queried on the wrong thread at the wrong time.
// We used to initialize as STA only _after_ initializing the application
// host, which loaded the settings. The settings needed to be loaded in MTA
// because we were using the Windows.Storage APIs. Since we're no longer
// doing that, we can safely init as STA before any WinRT dispatches.

Move tests to invoke te.exe directly instead of using VSTest runner (#4490)
Moves the tests from using the `vstest.console.exe` route to just using `te.exe`.

PROs:
- `te.exe` is significantly faster for running tests because the TAEF/VSTest adapter isn't great.
- Running through `te.exe` is closer to what our developers are doing on their dev boxes
- `te.exe` is how they run in the Windows gates.
- `te.exe` doesn't seem to have the sporadic `0x6` error code thrown during the tests where somehow the console handles get lost
- `te.exe` doesn't seem to repro the other intermittent issues that we have been having that are inscrutable. 
- Fewer processes in the tree (te is running anyway under `vstest.console.exe`, just indirected a lot
- The log outputs scroll live with all our logging messages instead of suppressing everything until there's a failure
- The log output is actually in the order things are happening versus vstest.

CONs:
- No more code coverage.
- No more test records in the ADO build/test panel.
- Tests really won't work inside Visual Studio at all.
- The log files are really big now
- Testing is not a test task anymore, just another script.

Refuting each CON:
- We didn't read the code coverage numbers
- We didn't look at the ADO test panel results or build-over-build velocities
- Tests didn't really work inside Visual Studio anyway unless you did the right incantations under the full moon.
- We could tone down the logging if we wanted at either the te.exe execution time (with a switch) or by declaring properties in the tests/classes/modules that are very verbose to not log unless it fails.
- I don't think anyone cares how they get run as long as they do.

Convert Tab to a WinRT type (#4350)
## Summary of the Pull Request
This PR will make the existing `Tab` class into a WinRT type. This will allow any XAML to simply bind to the `ObservableVector` of Tabs. 

This PR will be followed up with a future PR to change our TabView to use the ObservableVector, which will in turn eliminate the need for maintaining two vectors of Tabs. (We currently maintain `_tabs` in `TerminalPage` and we also maintain `TabView().TabViewItems()` at the same time as described here: #2740)

## References
#3922 

## PR Checklist
* [x] CLA signed.
* [x] Tests added/passed

## Detailed Description of the Pull Request / Additional comments
I've currently only exposed a Tab's Title and IconPath to keep things simple. I foresee XAML elements that bind to Tabs to only really need these two properties for displaying.

I've also converted `TerminalPage`'s `std::vector<std::shared_ptr> _tabs` into a `IObservableVector<winrt::TerminalPage::Tab> _tabs` just so that future PRs will have the ground set for binding to this vector of tabs.

## Validation Steps Performed
Played around with Tabs and Panes and all sorts of combinations of keybindings for interacting with tabs and dragging and whatnot, it all seemed fine! Tab Tests also all pass.

Add support for VT100 Auto Wrap Mode (DECAWM) (#3943)
## Summary of the Pull Request

This adds support for the [`DECAWM`](https://vt100.net/docs/vt510-rm/DECAWM) private mode escape sequence, which controls whether or not the output wraps to the next line when the cursor reaches the right edge of the screen. Tested manually, with [Vttest](https://invisible-island.net/vttest/), and with some new unit tests.

## Detailed Description of the Pull Request / Additional comments

The idea was to repurpose the existing `ENABLE_WRAP_AT_EOL_OUTPUT` mode, but the problem with that was it didn't work in VT mode - specifically, disabling it didn't prevent the wrapping from happening. This was because in VT mode the `WC_DELAY_EOL_WRAP` behaviour takes affect, and that bypasses the usual codepath where `ENABLE_WRAP_AT_EOL_OUTPUT` is checked,

To fix this, I had to add additional checks in the `WriteCharsLegacy` function (7dbefe06e41f191a0e83cfefe4896b66094c4089) to make sure the `WC_DELAY_EOL_WRAP` mode is only activated when `ENABLE_WRAP_AT_EOL_OUTPUT`  is also set.

Once that was fixed, though, another issue came to light: the `ENABLE_WRAP_AT_EOL_OUTPUT` mode doesn't actually work as documented. According to the docs, "if this mode is disabled, the last character in the row is overwritten with any subsequent characters". What actually happens is the cursor jumps back to the position at the start of the write, which could be anywhere on the line.

This seems completely broken to me, but I've checked in the Windows XP, and it has the same behaviour, so it looks like that's the way it has always been. So I've added a fix for this (9df98497ca38f7d0ea42623b723a8e2ecf9a4ab9), but it is only applied in VT mode.

Once that basic functionality was in place, though, we just needed a private API in the `ConGetSet` interface to toggle the mode, and then that API could be called from the `AdaptDispatch` class when the `DECAWM` escape sequence was received.

One last thing was to reenable the mode in reponse to a `DECSTR` soft reset. Technically the auto wrap mode was disabled by default on many of the DEC terminals, and some documentation suggests that `DECSTR` should reset it to that state, But most modern terminals (including XTerm) expect the wrapping to be enabled by default, and `DECSTR` reenables that state, so that's the behaviour I've copied.

## Validation Steps Performed

I've add a state machine test to confirm the `DECAWM` escape is dispatched correctly, and a screen buffer test to make sure the output is wrapped or clamped as appropriate for the two states.

I've also confirmed that the "wrap around" test is now working correctly in the _Test of screen features_ in Vttest.

## Detailed Description of the Pull Request / Additional comments

### Modifications to `InputStateMachineEngine`
I introduced various enum types...
- `CsiIntermediateCodes`: our supported intermediate codes. Currently only `<`
- `CsiEndCodes`: the last code used for SGR Mouse Mode
- `CsiMouseButtonCodes`: which button was pressed. Mutually exclusive. Buttons beyond button 11 are ambiguous.
- `CsiMouseModifierCodes`: bitfield of modifiers active for SGR Mouse Mode.

`CsiIntermediateCodes` is used first in `ActionCsiDispatch` to detect the VT Sequence. This kicks off a chain of function calls...
- `_GetXYPosition()`: figure out where the mouse was clicked
- `_UpdateSGRMouseButtonState`: read in what we found and update our internal state
- `_WriteMouseEvent()`: generate an INPUT_RECORD and send it off

### Modifications to Testing Suite
read below.
Also, made the test state a globally accessible/modifiable variable.

## Validation Steps Performed
Added tests that cover...
- button clicks
- button clicks with modifiers
- mouse movement
- mouse movement and entering/exiting a state where multiple buttons were pressed

Moved `FindText` to `UiaTextRangeBase`. Now that Search is a shared component (thanks #3279), I can just reuse it basically as-is.

#3279 - Make Search a shared component
#4018 - UiaTextRange Refactor

I removed it from the two different kinds of UiaTextRange and put it in the base class.

I needed a very minor change to ensure we convert from an inclusive end (from Search) to an exclusive end (in UTR).

Worked with `FindText` was globally messed with in windows.h. So we had to do a few weird things there (thanks Michael).

No need for additional tests because it _literally_ just sets up a Searcher and calls it.

Refactor UiaTextRange For Improved Navigation and Reliability (#4018)
## Summary of the Pull Request
This pull request is intended to achieve the following goals...
1) reduce duplicate code
2) remove static functions
3) improve readability
4) improve reliability
5) improve code-coverage for testing
6) establish functioning text buffer navigation in Narrator and NVDA

This also required a change to the wrapper class `XamlUiaTextRange` that has been causing issues with Narrator and NVDA.

See below for additional context.

## References
#3976 - I believe this might have been a result of improperly handling degenerate ranges. Fixed here.
#3895 - reduced the duplicate code. No need to separate into different files
#2160 - same as #3976 above
#1993 - I think just about everything is no longer static

## PR Checklist
* [x] Closes #3895, Closes #1993, Closes #3976, Closes #2160 
* [x] CLA signed
* [x] Tests added/passed

## Detailed Description of the Pull Request / Additional comments

### UiaTextRange
- converted endpoints into the COORD system in the TextBuffer coordinate space
- `start` is inclusive, `end` is exclusive. A degenerate range is when start == end.
- all functions are no longer static
- `MoveByUnit()` functions now rely on `MoveEndpointByUnit()` functions
- removed unnecessary typedefs like `Endpoint`, `ScreenInfoRow`, etc..
- relied more heavily on existing functionality from `TextBuffer` and `Viewport`

### XamlUiaTextRange
- `GetAttributeValue()` must return a special HRESULT that signifies that the requested attribute is not supported. This was the cause of a number of inconsistencies between Narrator and NVDA.
- `FindText()` should return `nullptr` if nothing was found. #4373 properly fixes this functionality now that Search is a shared module

### TextBuffer
- Word navigation functionality is entirely in `TextBuffer` for proper abstraction
- a total of 6 functions are now dedicated to word navigation to get a good understanding of the differences between a "word" in Accessibility and a "word" in selection

As an example, consider a buffer with this text in it:
"  word   other  "
In selection, a "word" is defined as the range between two delimiters, so the words in the example include ["  ", "word", "   ", "other", "  "].
In accessibility , a "word" includes the delimiters after a range of readable characters, so the words in the example include ["word   ", "other  "].

Additionally, accessibility word navigation must be able to detect if it is on the first or last word. This resulted in a slight variant of word navigation functions that return a boolean instead of a COORD.

Ideally, these functions can be consolidated, but that is too risky for a PR of this size as it can have an effect on selection.

### Viewport
- the concept of `EndExclusive` is added. This is used by UiaTextRange's `end` anchor as it is exclusive. To signify that the last character in the buffer is included in this buffer, `end` must be one past the end of the buffer. This is `EndExclusive`
- Since many functions check if the given `COORD` is in bounds, a flag must be set to allow `EndExclusive` as a valid `COORD` that is in bounds.

### Testing
- word navigation testing relies more heavily on TextBuffer tests
- additional testing was created for non-movement focused functions of UiaTextRange
- The results have been compared to Microsoft Word and some have been verified by UiAutomation/Narrator contacts as expected results.

A pair of fixes related to cursor movement in conpty (#4372)
## Summary of the Pull Request

This is a pair of related fixes to conpty. For both of these bugs, the root cause was that the cursor was getting set to Off in conpty. Without the `CursorBlinkerTimer`, the cursor would remain off, and frames that only had cursor movements would not update the cursor position in the terminal.

## References

## PR Checklist
* [x] Closes #4102 
* [x] Closes #2642
* [x] I work here
* [ ] Tests added/passed
* [n/a] Requires documentation to be updated

## Detailed Description of the Pull Request / Additional comments

Recall that there's a bunch of cursor state that's hard to parse without looking up:
* `Visibility` This controls whether the cursor is visible _at all_, regardless if it's been blinked on or off
* `Blinking` controls whether the blinker timer should do something, or leave the cursor alone.
* `IsOn`: When the cursor is blinking, this alternates between true and false. 

The trick here is that we only `TriggerCursorMoved` when the cursor is `On`, and there are some scenarios where the cursor is manually set to off. 

Fundamentally, these two bugs are similar cases, but they are triggered by different things:
* #2642 was caused by `DoSrvPrivateAllowCursorBlinking(false)` (`^[[?12l`) also manually turning the cursor off.
* #4102 was caused by the client calling `SetConsoleScreenBuffer` to change the active buffer. `win-curses` actually uses that API instead of the alt buffer.

Remove unneeded VT-specific control character handling (#4289)
## Summary of the Pull Request

This PR removes all of the VT-specific functionality from the `WriteCharsLegacy` function that dealt with control characters, since those controls are now handled in the state machine when in VT mode. It also removes most of the control character handling from the `Terminal::_WriteBuffer` method for the same reason.

## References

This is a followup to PR #4171

## Detailed Description of the Pull Request / Additional comments

There are four changes to the `WriteCharsLegacy` implementation:

1. The `TAB` character had special case handling in VT mode which is now no longer required. This fixes a bug in the Python REPL editor (when run from a cmd shell in Windows Terminal), which would prevent you tabbing past the end of the line. It also fixes #3971.

2. Following on from point 1, the `WC_NONDESTRUCTIVE_TAB` flag could also now be removed. It only ever applied in VT mode, in which case the `TAB` character isn't handled in `WriteCharsLegacy`, so there isn't a need for a non-destructive version.

3. There used to be special case handling for a `BS` character at the beginning of the line when in VT mode, and that is also no longer required. This fixes an edge-case bug which would prevent a glyph being output for code point 8 when `ENABLE_PROCESSED_OUTPUT` was disabled. 

4. There was quite a lot of special case handling for control characters in the "end-of-line wrap" implementation, which is no longer required. This fixes a bug which would prevent "low ASCII" characters from wrapping when output at the end of a line.

Then in the `Terminal::_WriteBuffer` implementation, I've simply removed all control character handling, except for `LF`. The Terminal is always in VT mode, so the control characters are always handled by the state machine. The exception for the `LF` character is simply because it doesn't have a proper implementation yet, so it still passes the character through to `_WriteBuffer`. That will get cleaned up eventually, but I thought that could wait for a later PR.

Finally, with the removal of the VT mode handling in `WriteCharsLegacy`, there was no longer a need for the `SCREEN_INFORMATION::InVTMode` method to be publicly accessible. That has now been made private.

## Validation Steps Performed

I've only tested manually, making sure the conhost and Windows Terminal still basically work, and confirming that the above-mentioned bugs are fixed by these changes.

Add just the test infrastructure bits from #4354 (#4382)
## Summary of the Pull Request

#4354 is a pretty complicated PR. It's got a bunch of conpty changes, but what it also has was some critical improvements to the roundtrip test suite. I'm working on some other bugfixes in the same area currently, and need these tests enhancements in those branches _now_. The rest of #4354 is complex enough that I don't trust it will get merged soon (if ever). However, these fixes _should_ be in regardless.

## Detailed Description of the Pull Request / Additional comments

This is four main changes:
* Enable conpty to be fully enabled in unittests. Just setting up a VT renderer isn't enough to trick the host into being in conpty mode - it also needs to have some other flags set.
* Some minor changes to `CommonState` to better configure the common test state for conpty
* Move some of the verify helpers from `ConptyRoundtripTests` into their own helper class, to be shared in multiple tests
* Add a `TerminalBufferTests` class, for testing the Terminal buffer directly (without conpty).

This change is really easier than

🛑 **STOP** 🛑 - have you read #3495 yet? If you haven't, go do that now.

This PR adds support for three initial sub-commands to the `wt.exe` application:
* `new-tab`: Used to create a new tab.
* `split-pane`: Used to create a new split.
* `focus-tab`: Moves focus to another tab.

These commands are largely POC to prove that the commandlines work. They're not totally finished, but they work well enough. Follow up work items will be filed to track adding support for additional parameters and subcommands

Important scenarios added:
* `wt -d .`: Open a new wt instance in the current working directory #878
* `wt -p <profile name>`: Create a wt instance running the given profile, to unblock  #576, #1357, #2339
* `wt ; new-tab ; split-pane -V`: Launch the terminal with multiple tabs, splits, to unblock #756

James Holderness e675de3a88 Add support for the DECSCNM screen mode (#3817)
## Summary of the Pull Request

This adds support for the [`DECSCNM`](https://vt100.net/docs/vt510-rm/DECSCNM.html) private mode escape sequence, which toggles the display between normal and reverse screen modes. When reversed, the background and foreground colors are switched. Tested manually, with [Vttest](https://invisible-island.net/vttest/), and with some new unit tests.

## References

This also fixes issue #72 for the most part, although if you toggle the mode too fast, there is no discernible flash.

## Detailed Description of the Pull Request / Additional comments

I've implemented this as a new flag in the `Settings` class, along with updates to the `LookupForegroundColor` and `LookupBackgroundColor` methods, to switch the returned foreground and background colors when that flag is set. 

It also required a new private API in the `ConGetSet` interface to toggle the setting. And that API is then called from the `AdaptDispatch` class when the screen mode escape sequence is received.

The last thing needed was to add a step to the `HardReset` method, to reset the mode back to normal, which is one of the `RIS` requirements.

Note that this does currently work in the Windows Terminal, but once #2661 is implemented that may no longer be the case. It might become necessary to let the mode change sequences pass through conpty, and handle the color reversing on the client side.
 
## Validation Steps Performed

I've added a state machine test to make sure the escape sequence is dispatched correctly, and a screen buffer test to confirm that the mode change does alter the interpretation of colors as expected.

I've also confirmed that the various "light background" tests in Vttest now display correctly, and that the `tput flash` command (in a bash shell) does actually cause the screen to flash.

James Holderness cbb87b98b7 Add support for the HPR and VPR escape sequences (#4297)
## Summary of the Pull Request

This PR adds support for the `HPR` and `VPR`  escape sequences from the VT510 terminal. `HPR` moves the cursor position forward by a given number of columns, and `VPR` moves the cursor position downward by a given number of rows. They're similar in function to the `CUF` and `CUD` escape sequences, except that they're not constrained by the scrolling margins.

## Detailed Description of the Pull Request / Additional comments

Most of the implementation is in the new `_CursorMovePosition` method that was created in PR #3628, so all we're really doing here is hooking up the escape sequences to call that method with the appropriate parameters.

## Validation Steps Performed

I've extended the existing state machine tests for CSI cursor movement to confirm that the `HPR` and `VPR` sequences are dispatched correctly, and also added screen buffer tests to make sure the movement is clamped by the screen boundaries and not the scrolling margins (we don't yet support horizontal margins, but the test is at least in place for when we do eventually add that support).

I've also checked the `HPR` and `VPR` tests in Vttest (under _Test non-VT100 / ISO-6429 cursor-movement_) and confirmed that they are now working as expected.

## Detailed Description of the Pull Request / Additional comments

Currently, it seems like CustomTextLayout::_CorrectGlyphRun generally assumes that glyphs and characters have a 1:1 mapping relationship - which holds true for most trivial scenarios with basic western scripts, and also many, but unfortunately not all, monospace "programming" fonts with programming ligatures.

This change makes terminal correctly processes glyphs that represents multiple characters, by properly accumulating the column counts of all these characters together (which I believe is more close to what this code originally intended to do).

There are still many issues existing in both CustomTextLayout as well as the TextBuffer, and the correct solution to them will likely demand large-scale changes, at least at the scale of #3578. I wish small changes like this can serve as a stop gap solution while we take our time to work on the long-term right thing.

* First, I started by writing a test where I could write output to the console  host and inspect what output came out of conpty. This is the `ConptyOutputTests` in the host unit tests.
* Then I got crazy and thought _"what if I could take that output and dump it straight into the `Terminal`"_? Hence, the `ConptyRoundtripTests` were born, into the TerminalCore unit tests.

Also, some other bits had to be updated:
* The renderer needed to be able to survive without a thread, so I hadded a simple check that it actually had a thread before calling `pThread->NotifyPaint`
* Bits in `CommonState` used `NTSTATUS_FROM_HRESULT` which did _not_ work outside the host project. Since the `NTSTATUS` didn't seem that important, I replaced that with a `HRESULT`
* `CommonState` likes to initialize the console to some _weird_ defaults. I added an optional param to let us just use the defaults.

WT crashes when an unparseable/invalid `backgroundImage` or `icon`
resource path is provided in `profiles.json`. This PR averts the crash
by the validating and correcting resource paths as a part of the
`_ValidateSettings()` function in `CascadiaSettings`.
`_ValidateSettings()` is run on start up and any time `profiles.json` is
changed, so a user can not change a file path and avoid the validation
step. 

When a bad `backgroundImage` or `icon` resource path is detected, a
warning screen will be presented.

References #4002, which identified a consistent repro for the crash.

To validate the resource, a `Windows::Foundation::Uri` object is
constructed with the path. The ctor will throw if the resource path is
invalid. Whether or not this validation method is robust enough is a
subject worth review. The correction method for when a bad resource path
is detected is to reset the `std::optional<winrt::hstring>` holding the
file path. 

The text in the warning display was cribbed from the text used when an
invalid `colorScheme` is used. Whether or not the case of a bad
background image file path warrants a warning display is a subject worth
review.

Ensured the repro steps in #4002 did not trigger a crash. Additionally,
some potential backdoor paths to a crash were tested: 

- Deleting the file of a validated background image file path
- Changing the actual file name of a validated background image file
  path
- Replacing the file of a validated background image file path with a
  non-image file (of the same name)
- Using a non-image file as a background image

In all the above cases WT does not crash, and instead defaults to the
background color specified in the profile's `colorScheme`. This PR does
not implement this recovery behavior (existing error catching code
does).

Closes #2329

James Holderness 0586955c88 Dispatch more C0 control characters from the VT state machine (#4171)
This commit moves the handling of the `BEL`, `BS`, `TAB`, and `CR`
controls characters into the state machine (when in VT mode), instead of
forwarding them on to the default string writer, which would otherwise
have to parse them out all over again.

This doesn't cover all the control characters, but `ESC`, `SUB`, and
`CAN` are already an integral part of the `StateMachine` itself; `NUL`
is filtered out by the `OutputStateMachineEngine`; and `LF`, `FF`, and
`VT`  are due to be implemented as part of PR #3271.

Once all of these controls are handled at the state machine level, we
can strip out all the VT-specific code from the `WriteCharsLegacy`
function, which should simplify it considerably. This would also let us
simplify the `Terminal::_WriteBuffer` implementation, and the planned
replacement stream writer for issue #780.

On the conhost side, the implementation is handled as follows:

* The `BS` control is dispatched to the existing `CursorBackward`
  method, with a distance of 1.
* The `TAB` control is dispatched to the existing `ForwardTab` method,
  with a tab count of 1.
* The `CR` control required a new dispatch method, but the
  implementation was a simple call to the new `_CursorMovePosition` method
  from PR #3628.
* The `BEL` control also required a new dispatch method, as well as an
  additional private API in the `ConGetSet` interface. But that's mostly
  boilerplate code - ultimately it just calls the `SendNotifyBeep` method.

On the Windows Terminal side, not all dispatch methods are implemented.

* There is an existing `CursorBackward` implementation, so `BS` works
  OK.
* There isn't a `ForwardTab` implementation, but `TAB` isn't currently
  required by the conpty protocol.
* I had to implement the `CarriageReturn` dispatch method, but that was
  a simple call to `Terminal::SetCursorPosition`.
* The `WarningBell` method I've left unimplemented, because that
  functionality wasn't previously supported anyway, and there's an
  existing issue for that (#4046).

## Validation Steps Performed

I've added a state machine test to confirm that the updated control
characters are now forwarded to the appropriate dispatch handlers. But
since the actual implementation is mostly relying on existing
functionality, I'm assuming that code is already adequately tested
elsewhere. That said, I have also run various manual tests of my own,
and confirmed that everything still worked as well as before.

James Holderness 2fec1787a0 Improve the VT cursor movement implementation (#3628)
## Summary of the Pull Request

Originally there were 3 different methods for implementing VT cursor movement, and between them they still couldn't handle some of the operations correctly. This PR unifies those operations into a single method that can handle every type of cursor movement, and which fixes some of the issues with the existing implementations. In particular it fixes the `CNL` and `CPL` operations, so they're now correctly constrained by the `DECSTBM` margins.

## References

If this PR is accepted, the method added here should make it trivial to implement the `VPR` and `HPR` commands in issue #3428.

## Detailed Description of the Pull Request / Additional comments

The new [`AdaptDispatch::_CursorMovePosition`](d6c4f35cf6/src/terminal/adapter/adaptDispatch.cpp (L169)) method is based on the proposal I made in issue #3428 for the `VPR` and `HPR` comands. It takes three arguments: a row offset (which can be absolute or relative), a column offset (ditto), and a flag specifying whether the position should be constrained by the `DECSTBM` margins.

To make the code more readable, I've implemented the offsets using [a `struct` with some `constexpr` helper functions for the construction](d6c4f35cf6/src/terminal/adapter/adaptDispatch.hpp (L116-L125)). This lets you specify the parameters with expressions like `Offset::Absolute(col)` or `Offset::Forward(distance)` which I think makes the calling code a little easier to understand.

While implementing this new method, I noticed a couple of issues in the existing movement implementations which I thought would be good to fix at the same time.

1. When cursor movement is constrained horizontally, it should be constrained by the buffer width, and not the horizontal viewport boundaries. This is an issue I've previously corrected in other parts of the codebase, and I think the cursor movement was one of the last areas where it was still a problem.

2. A number of the commands had range and overflow checks for their parameters that were either unnecessary (testing for a condition that could never occur) or incorrect (if an operation overflows, the correct behavior is to clamp it, and not just fail). The new implementation handles legitimate overflows correctly, but doesn't check for impossible ranges.

Because of the change of behavior in point 1, I also had to update the implementations of [the `DECSC` and `CPR` commands](9cf7a9b577) to account for the column offset now being relative to the buffer and not the viewport, otherwise those operations would no longer work correctly.

## Validation Steps Performed

Because of the two changes in behavior mentioned above, there were a number of adapter tests that stopped working and needed to be updated. First off there were those that expected the column offset to be relative to the left viewport position and constrained by the viewport width. These now had to be updated to [use the full buffer width](49887a3589) as the allowed horizontal extent.

Then there were all the overflow and out-of-range tests that were testing conditions that could never occur in practice, or where the expected behavior that was tested was actually incorrect. I did spend some time trying to see if there was value in updating these tests somehow, but in the end I decided it was best to just [drop them](6e80d0de19) altogether.

For the `CNL` and `CPL` operations, there didn't appear to be any existing tests, so I added some [new screen buffer tests](d6c4f35cf6) to check that those operations now work correctly, both with and without margins.

## Detailed Description of the Pull Request / Additional comments

I've added a `LineFeed` method to the `ITermDispatch` interface, with an enum parameter specifying the required line feed type (i.e. with carriage return, without carriage return, or dependent on the [`LNM` mode](https://vt100.net/docs/vt510-rm/LNM.html)). The output state machine can then call that method to handle the various line feed control characters (parsed in the `ActionExecute` method), as well the `NEL` and `IND` escape sequences (parsed in the `ActionEscDispatch` method).

The `AdaptDispatch` implementation of `LineFeed` then forwards the call to a new `PrivateLineFeed` method in the `ConGetSet` interface, which simply takes a bool parameter specifying whether a carriage return is required or not. In the case of mode-dependent line feeds, the `AdaptDispatch` implementation determines whether the return is necessary or not, based on the existing _AutoReturnOnNewLine_ setting (which I'm obtaining via another new `PrivateGetLineFeedMode` method).

Ultimately we'll want to support changing the mode via the [`LNM` escape sequence](https://vt100.net/docs/vt510-rm/LNM.html), but there's no urgent need for that now. And using the existing _AutoReturnOnNewLine_ setting as a substitute for the mode gives us backwards compatible behaviour, since that will be true for the Windows shells (which expect a linefeed to also generate a carriage return), and false in a WSL bash shell (which won't want the carriage return by default).

As for the actual `PrivateLineFeed` implementation, that is just a simplified version of how the line feed would previously have been executed in the `WriteCharsLegacy` function. This includes setting the cursor to "On" (with `Cursor::SetIsOn`), potentially clearing the wrap property of the line being left (with `CharRow::SetWrapForced` false), and then setting the new position using `AdjustCursorPosition` with the _fKeepCursorVisible_ parameter set to false.

I'm unsure whether the `SetIsOn` call is really necessary, and I think the way the forced wrap is handled needs a rethink in general, but for now this should at least be compatible with the existing behaviour.

Finally, in order to make this all work in the _Windows Terminal_ app, I also had to add a basic implementation of the `ITermDispatch::LineFeed` method in the `TerminalDispatch` class. There is currently no need to support mode-specific line feeds here, so this simply forwards a `\n` or `\r\n` to the `Execute` method, which is ultimately handled by the `Terminal::_WriteBuffer` implementation.

## Validation Steps Performed

I've added output engine tests which confirm that the various control characters and escape sequences trigger the dispatch method correctly. Then I've added adapter tests which confirm the various dispatch options trigger the `PrivateLineFeed` API correctly. And finally I added some screen buffer tests that check the actual results of the `NEL` and `IND` sequences, which covers both forms of the `PrivateLineFeed` API (i.e. with and without a carriage return).

I've also run the _Test of cursor movements_ in the [Vttest](https://invisible-island.net/vttest/) utility, and confirmed that screens 1, 2, and 5 are now working correctly. The first two depend on `NEL` and `IND` being supported, and screen 5 requires the `VT` control character.

## Detailed Description of the Pull Request / Additional comments

In `SCREEN_INFORMATION::ResizeScreenBuffer`, the screenbuffer needs to create a new buffer, and copy the contents of the old buffer into the new one. I'm moving that "copy contents from the old buffer to the new one" step to it's own helper, as a static function on `TextBuffer`. That way, when the time comes to implement this for the Terminal, the hard part of the code will already be there.

## Validation Steps Performed

mcpiroman 1ca29128d4 Fix redundant CR in formatted text copy (#4190)
## Summary of the Pull Request

When `GenHTML` or `GenRTF` encountered an empty line, they assumed that `CR` is the last character of the row and wrote it, even though in general `CR` and `LF` just break the line and instead of them either `<BR>` in HTML or `\line` in RTF is written. Don't know how I missed that in #2038.

Another question is whether the `TextAndColor` structure which these methods receive and which is generated by `TextBuffer::GetTextForClipboard` should really contain `\r\n` at the end of each row. I think it'd be cleaner if it didn't esp. that afaik these last 2 characters don't have associated valid color information.

James Holderness bf86a961f0 Reverse the behavior of the IS_GLYPH_CHAR macro so its function now matches its name. (#4209)
## Summary of the Pull Request

This PR reverses the behaviour of the `IS_GLYPH_CHAR` macro, so it now actually returns true if the given char is a glyph, and false if it isn't. Previously it returned the opposite of that, which meant it had to be called as `!IS_GLYPH_CHAR` to get the correct result.

## Detailed Description of the Pull Request / Additional comments

The original implementation returned true if the given character was a C0 control, or a DEL:

    #define IS_GLYPH_CHAR(wch) (((wch) < L' ') || ((wch) == 0x007F))

It's now the exact opposite, so returns true for characters that are _not_ C0 controls, and are not the DEL character either: 

    #define IS_GLYPH_CHAR(wch) (((wch) >= L' ') && ((wch) != 0x007F))

The macro was only used in one place, where is was being called as `!IS_GLYPH_CHAR` when the intent was actually to test whether the char _was_ a glyph. That code could now be updated to remove the `!`, so it makes more sense.

## Validation Steps Performed

I've just tested manually and confirmed that basic output of text and control chars still worked as expected in a conhost shell.

Michael Niksa 4129ceb904 stab in the dark to fix x86 tests. (#4202)
## Summary of the Pull Request
Perform checking on `std::basic_string_view<T>.substr()` calls to
prevent running out of bounds and sporadic Privileged Instruction throws
during x86 tests.

## PR Checklist
* [x] Closes the x86 tests failing all over the place since #4125 for no
  apparent reason
* [x] I work here
* [x] Tests pass 

## Detailed Description of the Pull Request / Additional comments
It appears that not all `std::basic_string_view<T>.substr()` calls are
created equally. I rooted around for other versions of the code in our
source tree and found several versions that were less careful about
checking the start position and the size than the one that appears when
building locally on dev machines. 

My theory is that one of these older versions is deployed somewhere in
the CI. Instead of clamping down the size parameter appropriately or
throwing correctly when the position is out of bounds, I believe that
it's just creating a substring with a bad range over an
invalid/uninitialized memory region. Then when the test operates on
that, sometimes it turns out to trigger the privileged instruction
NTSTATUS error we are seeing in CI.

## Test Procedure
1. Fixed the thing
2. Ran the CI and it worked
3. Reverted everything and turned off all of the CI build except just
   the parser tests (and supporting libraries)
4. Ran CI and it failed
5. Put the fix back on top (cherry-pick)
6. It worked.
7. Ran it again.
8. It worked.
9. Turn all the rest of the CI build back on

## Summary of the Pull Request

## Detailed Description of the Pull Request / Additional comments

Unittesting for the TerminalApp project has been a horrifying process to try getting everything pieced together just right. Dependencies need to get added to manifests, binplaced correctly, and XAML resources need to get compiled together as well. In addition, using a MUX `Application` (as opposed to the Windows.UI.Xaml `Application`) has led to additional problems. 

This was always a horrifying house of cards for us. Turns out, the reason this was so horrible is that the test infrastructure for doing what we're doing _literally didn't exist_ when I started doing all that work last year.

So, with help from the TAEF team, I was able to get rid of our entire house of cards, and use a much simpler project to build and run the tests.

Unfortunately, the latest TAEF release has a minor bug in it's build rules, and only publishes the x86 version of a dll we need from them. But, the rest of this PR works for x86, and I'll bump this when that updated version is available. We should be able to review this even in the state it's in.

## Detailed Description of the Pull Request / Additional comments
My thought pattern here was to minimally disturb the existing code where possible. So where I could, I converted existing functions into coroutine using functions (like in the [core example](https://github.com/microsoft/terminal/issues/3919#issue-536598706)). For ~the most part~ all instances, I used the format where [`this` is accessed safely within a locked scope](https://github.com/microsoft/terminal/issues/3919#issuecomment-564730620). Some function signatures were changed to take objects by value instead of reference, so the coroutines don't crash when the objects are accessed past their original lifetime. The [copy](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalApp/TerminalPage.cpp#L1132) and [paste](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalApp/TerminalPage.cpp#L1170) event handler entry points were originally set to a high priority; however, the WinRT coroutines don't appear to support a priority scheme so this priority setting was not preserved in the translation.

Dustin L. Howett (MSFT) 8a21698c35 Don't generate WSL distributions for docker-desktop* (#4156)
These utility distributions are used by Docker for Windows' WSL2
integration. They are not intended for user consumption.

* [x] Closes #3556
* [x] CLA signed.
* [x] Tests added/passed
* [x] Requires documentation to be updated
* [x] I've discussed this with core contributors already.

There is a minimal chance that a user _has_ a distribution named `docker-desktop` or some superstring thereof, but this is taken as an acceptable level of risk.

wsl: actually close the pipe handle for wsl.exe, but only once (#4158)
We were eating an exception on exit in debug mode because we were using
wil to clean up half of a named pipe we'd already handed ownership of
over to the CRT. The CRT likes to tie up all its loose ends when it gets
unloaded, so it was coming along at exit and closing the handle again.
Big no-no.

Introduce til::some (#4123)
## Summary of the Pull Request
Introduces a type that is basically an array (stack allocated, fixed size) that reports size based on how many elements are actually filled (from the front), iterates only the filled ones, and has some basic vector push/pop semantics.

* [ ] I'd love to roll this out to SomeViewports.... maybe in this commit or a follow on one.
* [ ] We need a TIL tests library and I should test this there. 

## Detailed Description of the Pull Request / Additional comments
The original gist of this was used for `SomeViewports` which was a struct to hold between 0 and 4 viewports, based on how many were left after subtraction (since rectangle subtraction functions in Windows code simply fail for resultants that yield >=2 rectangle regions.)

I figured now that we're TIL-ifying useful common utility things that this would be best suited to a template because I'm certain there are other circumstances where we would like to iterate a partially filled array and want it to not auto-resize-up like a vector would.

Michael Niksa e9827f3884 Merged PR 4177605: [Git2Git] Merged PR 4177564: Use CopyTo when returning WindowUiaProvider child to ensure proper ref count
[Git2Git] Merged PR 4177564: Use CopyTo when returning WindowUiaProvider child to ensure proper ref count

`WindowUiaProvider` was giving up copies of the pointer to its child `ScreenInfoUiaProvider` without `AddRef`ing them. This means that the receiver of those pointers was `Release`ing them at some later time, causing the internal count to decrement, sometimes all the way to zero.

The crash occurs when a `Signal` comes in and `WindowUiaProvider` attempts to resolve it through `ScreenInfoUiaProvider` but it is already gone because it has been `Release`d all the way to 0 (despite the pointer still being held by `WindowUiaProvider`). The crash then manifests in a bunch of different stacks depending on what part of `ScreenInfoUiaProvider` gets the most unlucky at executing through the now uninitialized memory.

I searched the codebase for more instances of `*ppProvider` and assignments of bare pointers. @<Carlos Zamora> appears to have already got nearly all of them in a previous refactoring operation to prepare our classes to use `WRL` more broadly. These were the only two I could find remaining.

mcpiroman d4c527607a Snap to character grid when resizing window (#3181)
When user resizes window, snap the size to align with the character grid
(like e.g. putty, mintty and most unix terminals). Properly resolves
arbitrary pane configuration (even with different font sizes and
padding) trying to align each pane as close as possible.

It also fixes terminal minimum size enforcement which was not quite well
handled, especially with multiple panes.

This PR does not however try to keep the terminals aligned at other user
actions (e.g. font change or pane split). That is to be tracked by some
other activity.

Snapping is resolved in the pane tree, recursively, so it (hopefully)
works for any possible layout.

Along the way I had to clean up some things as so to make the resulting
code not so cumbersome:
1. Pane.cpp: Replaced _firstPercent and _secondPercent with single
   _desiredSplitPosition to reduce invariants - these had to be kept in
   sync so their sum always gives 1 (and were not really a percent). The
   desired part refers to fact that since panes are aligned, there is
   usually some deviation from that ratio.
2. Pane.cpp: Fixed _GetMinSize() - it was improperly accounting for
   split direction
3. TerminalControl: Made dedicated member for padding instead of
   reading it from a control itself. This is because the winrt property
   functions turned out to be slow and this algorithm needs to access it
   many times. I also cached scrollbar width for the same reason.
4. AppHost: Moved window to client size resolution to virtual method,
   where IslandWindow and NonClientIslandWindow have their own
   implementations (as opposite to pointer casting).

One problem with current implementation is I had to make a long call
chain from the window that requests snapping to the (root) pane that
implements it: IslandWindow -> AppHost's callback -> App ->
TerminalPage -> Tab -> Pane. I don't know if this can be done better.

## Validation Steps Performed
Spam split pane buttons, randomly change font sizes with ctrl+mouse
wheel and drag the window back and forth.

Closes #2277

Michael Niksa 913c5ec744 Correct passthrough sequences after refactor (#4125)
## Summary of the Pull Request
When refactoring the `StateMachine::ProcessString` algorithm to use safer structures, I made an off-by-one error when attempting to simplify the loop. 

## References
- Introduced in #3956 

## PR Checklist
* [x] Closes #4116
* [x] I work here.
* [x] Tests added/passed
* [x] No documentation
* [x] I'm a core contributor.

## Detailed Description of the Pull Request / Additional comments
The algorithm in use exploited holding onto some pointers and sizes as it rotated around the loop to call back as member variables in the pass-through function `FlushToTerminal`. 

As a part of the refactor, I adjusted to persisting a `std::wstring_view` of the currently processing string instead of pointer/size. I also attempted to simplify the loop at the same time as both the individual and group branches were performing some redundant operations in respect to updating the "run" length. 

Turns out, I made a mistake here. I wrote it so it worked correctly for the bottom half where we transition from bulk printing to an escape but then I messed up the top case.

## Validation Steps Performed
- [x] Manual validation of the exact command given in the bug report.
- [x] Wrote automated tests to validate both paths through the `ProcessString` loop that work with the `_run` variable.

Leonard Hecker 83f8973000 Fix IME/CoreTextEditContext not being reset properly (#4140)
The first argument to `NotifyTextChanged` incorrectly was `[0,0]`
instead of the length of the text to be removed from the
`CoreTextEditContext`.

Best source of documentation for `NotifyTextChanged`:
https://docs.microsoft.com/en-us/windows/uwp/design/input/custom-text-input#overriding-text-updates

FYI @DHowett-MSFT (just in case): C++/WinRT uses `winrt::param::hstring`
for string parameters which intelligently borrows strings. As such you
can simply pass a `std::wstring` to most WinRT methods without the need
of having to allocate an intermediate `hstring`. 🙂

the issue doesn't happen anymore.

The terminal will use the system setting to determine the number of lines to scroll at a time.
This can be overridden by adding rowsToScroll to app global settings file.
terminal will use the system setting if the app setting is 0, or not specified. No restart is needed to reflect setting changes in system or the settings file.

The default was hardcoded to 4 in the code with a todo comment. 1 works better on precision touchpads, where 4 scrolls too fast.

## Summary of the Pull Request

This removes support for the the VT52 cursor movement operations, in preparation for PR #3271, since the cursor back operation conflicts with the VT100 [`IND`](https://vt100.net/docs/vt510-rm/IND.html) sequence, which we're planning to add. Eventually these ops will be brought back as part of a proper VT52 implementation, when appropriately activated by the [`DECANM`](https://vt100.net/docs/vt510-rm/DECANM.html) mode.

## PR Checklist

* [x] Am a core contributor.

## Detailed Description of the Pull Request / Additional comments
This is in support of hopefully turning audit mode on to more projects. If I turned it on, it would immediately complain about certain classes of issues like pointer and size, pointer math, etc. The changes in this refactoring will eliminate those off the top.

Additionally, this has caught a bunch of comments all over the VT classes that weren't updated to match the parameters lists.

Additionally, this has caught a handful of member variables on classes that were completely unused (and now gone).

Additionally, I'm killing almost all hungarian and shortening variable names. I'm only really leaving 'p' for pointers.

Additionally, this is vaguely in support of a future where we can have "infinite scrollback" in that I'm moving things to size_t across the board. I know it's a bit of a memory cost, but all the casting and moving between types is error prone and unfun to save a couple bytes.

Mike Griese 2e26c3e0c9 Add support for "Automatic" splits (#4025)
## Summary of the Pull Request

Adds support for `auto` as a potential value for a `splitPane` keybinding's `split` argument. For example:

```json
        { "keys": [ "ctrl+shift+z" ], "command": { "action": "splitPane", "profile": "matrix", "commandline": "cmd.exe", "split":"auto" } },
```

When set to `auto`, Panes will decide which direction to split based on the available space within the terminal. If the pane is wider than it is tall, the pane will introduce a new vertical split (and vice-versa).

## Summary of the Pull Request

This adds support for the [`DECALN`](https://vt100.net/docs/vt510-rm/DECALN.html) escape sequence, which produces a kind of test pattern, originally used on VT terminals to adjust the screen alignment.

## Detailed Description of the Pull Request / Additional comments

To start with, the `ActionEscDispatch` method in the `OutputStateMachineEngine` needed to be extended to check for a new intermediate type (`#`). Then when that intermediate is followed by an `8`, it dispatches to a new `ScreenAlignmentPattern` method in the `ITermDispatch` interface.

The implementation of the `ScreenAlignmentPattern` itself is fairly simple. It uses the recently added `PrivateFillRegion` API to fill the screen with the character `E` using default attributes. Then in addition to that, a bunch of VT properties are reset:

* The meta/extended attributes are reset (although the active colors must be left unchanged).
* The origin mode is set to absolute positioning.
* The scrolling margins are cleared.
* The cursor position is moved to home.

## Validation Steps Performed

I've added a screen buffer test that makes sure the `DECALN` sequence fills the screen with the correct character and attributes, and that the above mentioned properties are all updated appropriately.

I've also tested in Vttest, and confirmed that the first two pages of the _Test of cursor movements_ are now showing the frame of E's that are expected there.

These functionalities are included in the search experience. 
1. Search in Terminal text buffer. 
2. Automatic wrap-around. 
3. Search up or down switch by clicking different buttons.
4. Search case sensitively/insensitively by clicking a button.                                                                                                                                                S. Move the search box to the top/bottom by clicking a button. 
6. Close by clicking 'X'. 
7. Open search by ctrl + F.

When the searchbox is open, the user could still interact with the terminal by clicking the terminal input area. 

While I already have the search functionalities, currently there are still some known to-do works and I will keep updating my PR:

1. Optimize the search box UI, this includes:
                                                  1) Theme adaptation. The search box background and font color 
                                                       should change according to the theme, 
                                                  2) Add background. Currently the elements in search box are all
                                                      transparent. However, we need a background. 
                                                  3) Move button should be highlighted once clicked. 
2. Accessibility: search process should be able to performed without mouse. Once the search box is focused, the user should be able to navigate between all interactive elements on the searchbox using keyboard. 

<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->

To test:
1. checkout this branch.
2. Build the project. 
3. Start Windows Terminal and press Ctrl+F
4. The search box should appear on the top right corner.

## Detailed Description of the Pull Request / Additional comments

When the non-client island window is maximized and has the WS_OVERLAPPEDWINDOW style, SetWindowPos is "lying": the position ends up being offset compared to the one we gave it (found by debugging). So I changed it to use WS_POPUP like the client island window was already doing. But now it has the Vista frame that appears briefly when entering/exiting full screen like the client island window.

<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
An asynchronous event handler capturing raw `this` in `TermControl` was causing an exception to be thrown when a scroll update event occurred after closing the active tab. This PR replaces all non-auto_revoke lambda captures in `TermControl` to capture (and validate) a `winrt::weak_ref` instead of using raw `this`.

## Detailed Description of the Pull Request / Additional comments
`TermControl` is already a WinRT type so no changes were required to enable the `winrt::weak_ref` functionality. There was only one strange change I had to make. In the destructor's helper function `Close`, I had to remove two calls to [`Stop`](https://docs.microsoft.com/en-us/uwp/api/windows.ui.xaml.dispatchertimer.stop#Windows_UI_Xaml_DispatcherTimer_Stop) which were throwing under [some circumstances](https://github.com/microsoft/terminal/issues/2947#issuecomment-562914135). Fortunately, these calls don't appear to be critical, but definitely a spot to look into when reviewing this PR.

Beyond scrolling, any anomalous crash related to the following functionality while closing a tab or WT may be fixed by this PR:
- Settings updating
- Changing background color

Enable Word Navigation in UiaTextRange (#3659)
Enables support for word navigation when using an automation client (i.e.: Narrator, etc...). Specifically, adds this functionality to the UiaTextRange class. The only delimiter used is whitespace because that's how words are separated in English.

# General "Word Movement" Expectations
The resulting text range should include any word break characters that are present at the end of the word, but before the start of the next word. (Source)

If you already are on a word, getting the "next word" means you skip the word you are on, and highlight the upcoming word appropriately. (similar idea when moving backwards)


# Word Expansion
Since word selection is supposed to detect word delimiters already, I figured I'd reuse that code. I moved it from TerminalCore to the TextBuffer.

Then I built on top of it by adding an optional additional parameter that decides if you want to include...
- the delimiter run when moving forward
- the character run when moving backwards
It defaults to false so that we don't have to care when using it in selection. But we change it to true when using it in our UiaTextRange

# UiaTextRange
The code is based on character movement. This allows us to actually work with boundary conditions.

The main thing to remember here is that each text range is recorded as a MoveState. The text range is most easily defined when you think about the start Endpoint and the end Endpoint. An Endpoint is just a linear 1-dimensional indexing of the text buffer. Examples:
- Endpoint 0 --> (0,0)
- Endpoint 79 --> (79,0) (when the buffer width is 80)
- Endpoint 80 -->(0,1) (when the buffer width is 80)
- When moving forward, the strategy is to focus on moving the end Endpoint. That way, we properly get the indexing for the "next" word (this also fixes a wrapping issue). Then, we update the start Endpoint. (This is reversed for moving backwards).
- When moving a specific Endpoint, we just have a few extra if statements to properly adjust for moving start vs end.

# Hooking it up
All we really had to do is add an enum. This part was super easy :)

I originally wanted the delimiters to be able to be defined. I'm not so sure about that anymore. Either way, I hardcoded our delimiter into a variable so if we ever want to expand on it or make that customizable, we just modify that variable.

# Defining your own word delimiters

- Import a word delimiter into the constructor of the ScreenInfoUiaProvider (SIUP)
  - This defines a word delimiter for all the UiaTextRanges (UTR) created by in this context
- import a word delimiter into the UTR directly
  - this provides more control over what a "word" is
  - this can be useful if you have an idea of what text a particular UTR will encounter and you want to customize the word navigation for it (i.e consider adding / or \\ for file paths)

The default param of " " is scattered throughout because this is the word delimiter used in the English language.

James Holderness 6f21f30951 Don't allow a linefeed to scroll when outside DECSTBM margins (#3704)
## Summary of the Pull Request

When the `DECSTBM` margins are set, scrolling should only allowed within
those margins. So if the cursor is below the bottom margin, it should
just be clamped when it tries to move down from the bottom line of the
viewport, instead of scrolling the screen up. This PR implements that
restriction, i.e. it prevents scrolling taking place outside the
`DECSTBM` margins, which was previously allowed.

## PR Checklist
* [x] Closes #2657
* [x] CLA signed.
* [x] Tests added/passed

## Detailed Description of the Pull Request / Additional comments

This simply adds a condition in the `AdjustCursorPosition` function to
check if the cursor is moving below the bottom of the viewport when the
margins are set. If so, it clamps the y coordinate to the bottom line of
the viewport.

The only time it's acceptable for scrolling to happen when margins are
set, is if the scrolling is taking place within those margins. But those
cases would already have been handled earlier in the function (in the
`fScrollDown` or `scrollDownAtTop` conditions), and thus the y
coordinate would have already been prevented from moving out of the
viewport.

## Validation Steps Performed

I've added some screen buffer tests to confirm this new behaviour, and
I've also checked the test case from the initial bug report (#2657) and
made sure it now matches the results in XTerm.

Attach UiaRenderer and Fire Selection Changed Events (#2989)
This PR makes use of the UiaRenderer by attaching it to the TerminalControl and setting up selectionChanged events for accessibility.

Part 1: attaching the UiaRenderer
The uiaRenderer is treated very similarly to the dxRenderer. We have a unique_ptr ref to it in the TermControl. This gets populated when the TermControlAutomationPeer is created (thus enabling accessibility).

To prevent every TermControl from sending signals simultaneously, we specifically only enable whichever one is in an active pane.

The UiaRenderer needs to send encoded events to the automation provider (in this case, TermControlAutomationPeer). We needed our own automation events so that we can reuse this model for ConHost. This is the purpose of IUiaEventDispatcher.

We need a dispatcher for the UiaRenderer. Otherwise, we would do a lot of work to find out when to fire an event, but we wouldn't have a way of doing that.

Part 2: hooking up selection events
This provides a little bit of polish to hooking it up before. Primarily to actually make it work. This includes returning S_FALSE instead of E_NOTIMPL.

The main thing here really is just how to detect if a selection has changed. This also shows how clean adding more events will be in the future!

James Holderness 381b11521a Correct fill attributes when scrolling and erasing (#3100)
## Summary of the Pull Request

Operations that erase areas of the screen are typically meant to do so using the current color attributes, but with the rendition attributes reset (what we refer to as meta attributes). This also includes scroll operations that have to clear the area of the screen that has scrolled into view. The only exception is the _Erase Scrollback_ operation, which needs to reset the buffer with the default attributes. This PR updates all of these cases to apply the correct attributes when scrolling and erasing.

## Detailed Description of the Pull Request / Additional comments

My initial plan was to use a special case legacy attribute value to indicate the "standard erase attribute" which could safely be passed through the legacy APIs. But this wouldn't cover the cases that required default attributes to be used. And then with the changes in PR #2668 and #2987, it became clear that our requirements could be better achieved with a couple of new private APIs that wouldn't have to depend on legacy attribute hacks at all.

To that end, I've added the `PrivateFillRegion` and `PrivateScrollRegion` APIs to the `ConGetSet` interface. These are just thin wrappers around the existing `SCREEN_INFORMATION::Write` method and the `ScrollRegion` function respectively, but with a simple boolean parameter to choose between filling with default attributes or the standard erase attributes (i.e the current colors but with meta attributes reset).

With those new APIs in place, I could then update most scroll operations to use `PrivateScrollRegion`, and most erase operations to use `PrivateFillRegion`.

The functions affected by scrolling included:
* `DoSrvPrivateReverseLineFeed` (the RI command)
* `DoSrvPrivateModifyLinesImpl` (the IL and DL commands)
* `AdaptDispatch::_InsertDeleteHelper` (the ICH and DCH commands)
* `AdaptDispatch::_ScrollMovement` (the SU and SD commands)

The functions affected by erasing included:
* `AdaptDispatch::_EraseSingleLineHelper` (the EL command, and most ED variants)
* `AdaptDispatch::EraseCharacters` (the ECH command)

While updating these erase methods, I noticed that both of them also required boundary fixes similar to those in PR #2505 (i.e. the horizontal extent of the erase operation should apply to the full width of the buffer, and not just the current viewport width), so I've addressed that at the same time.

In addition to the changes above, there were also a few special cases, the first being the line feed handling, which required updating in a number of places to use the correct erase attributes:

* `SCREEN_INFORMATION::InitializeCursorRowAttributes` - this is used to initialise the rows that pan into view when the viewport is moved down the buffer.
* `TextBuffer::IncrementCircularBuffer` - this occurs when we scroll passed the very end of the buffer, and a recycled row now needs to be reinitialised.
* `AdjustCursorPosition` - when within margin boundaries, this relies on a couple of direct calls to `ScrollRegion` which needed to be passed the correct fill attributes.

The second special case was the full screen erase sequence (`ESC 2 J`), which is handled separately from the other ED sequences. This required updating the `SCREEN_INFORMATION::VtEraseAll` method to use the standard erase attributes, and also required changes to the horizontal extent of the filled area, since it should have been clearing the full buffer width (the same issue as the other erase operations mentioned above).

Finally, there was the `AdaptDispatch::_EraseScrollback` method, which uses both scroll and fill operations, which could now be handled by the new `PrivateScrollRegion` and `PrivateFillRegion` APIs. But in this case we needed to fill with the default attributes rather than the standard erase attributes. And again this implementation needed some changes to make sure the full width of the active area was retained after the erase, similar to the horizontal boundary issues with the other erase operations.

Once all these changes were made, there were a few areas of the code that could then be simplified quite a bit. The `FillConsoleOutputCharacterW`, `FillConsoleOutputAttribute`, and `ScrollConsoleScreenBufferW` were no longer needed in the `ConGetSet` interface, so all of that code could now be removed. The `_EraseSingleLineDistanceHelper` and `_EraseAreaHelper` methods in the `AdaptDispatch` class were also no longer required and could be removed.

Then there were the hacks to handle legacy default colors in the `FillConsoleOutputAttributeImpl` and `ScrollConsoleScreenBufferWImpl` implementations. Since those hacks were only needed for VT operations, and the VT code no longer calls those methods, there was no longer a need to retain that behaviour (in fact there are probably some edge cases where that behaviour might have been considered a bug when reached via the public console APIs). 

## Validation Steps Performed

For most of the scrolling operations there were already existing tests in place, and those could easily be extended to check that the meta attributes were correctly reset when filling the revealed lines of the scrolling region.

In the screen buffer tests, I made updates of that sort to  the `ScrollOperations` method (handling SU, SD, IL, DL, and RI), the `InsertChars` and `DeleteChars` methods (ICH and DCH), and the `VtNewlinePastViewport` method (LF). I also added a new `VtNewlinePastEndOfBuffer` test to check the case where the line feed causes the viewport to pan past the end of the buffer.

The erase operations, however, were being covered by adapter tests, and those aren't really suited for this kind of functionality (the same sort of issue came up in PR #2505). As a result I've had to reimplement those tests as screen buffer tests.

Most of the erase operations are covered by the `EraseTests` method, except the for the scrollback erase which has a dedicated `EraseScrollbackTests` method. I've also had to replace the `HardReset` adapter test, but that was already mostly covered by the `HardResetBuffer` screen buffer test, which I've now extended slightly (it could do with some more checks, but I think that can wait for a future PR when we're fixing other RIS issues).

Mike Griese dd1c7b3e52 Add support for new panes with specifc profiles and other settings overrides (#3825)
## Summary of the Pull Request


This enables the user to set a number of extra settings in the `NewTab` and `SplitPane` `ShortcutAction`s, that enable customizing how a new terminal is created at runtime. The following four properties were added:
* `profile`
* `commandline`
* `tabTitle`
* `startingDirectory`

`profile` can be used with either a GUID or the name of a profile, and the action will launch that profile instead of the default.

`commandline`, `tabTitle`, and `startingDirectory` can all be used to override the profile's values of those settings. This will be more useful for #607.

With this PR, you can make bindings like the following:

```json

{ "keys": ["ctrl+a"], "command": { "action": "splitPane", "split": "vertical" } },
{ "keys": ["ctrl+b"], "command": { "action": "splitPane", "split": "vertical", "profile": "{6239a42c-1111-49a3-80bd-e8fdd045185c}" } },
{ "keys": ["ctrl+c"], "command": { "action": "splitPane", "split": "vertical", "profile": "profile1" } },
{ "keys": ["ctrl+d"], "command": { "action": "splitPane", "split": "vertical", "profile": "profile2" } },
{ "keys": ["ctrl+e"], "command": { "action": "splitPane", "split": "horizontal", "commandline": "foo.exe" } },
{ "keys": ["ctrl+f"], "command": { "action": "splitPane", "split": "horizontal", "profile": "profile1", "commandline": "foo.exe" } },
{ "keys": ["ctrl+g"], "command": { "action": "newTab" } },
{ "keys": ["ctrl+h"], "command": { "action": "newTab", "startingDirectory": "c:\\foo" } },
{ "keys": ["ctrl+i"], "command": { "action": "newTab", "profile": "profile2", "startingDirectory": "c:\\foo" } },
{ "keys": ["ctrl+j"], "command": { "action": "newTab", "tabTitle": "bar" } },
{ "keys": ["ctrl+k"], "command": { "action": "newTab", "profile": "profile2", "tabTitle": "bar" } },
{ "keys": ["ctrl+l"], "command": { "action": "newTab", "profile": "profile1", "tabTitle": "bar", "startingDirectory": "c:\\foo", "commandline":"foo.exe" } }
```

## References

This is a lot of work that was largely started in pursuit of #607. We want people to be able to override these properties straight from the commandline. While they may not make as much sense as keybindings like this, they'll make more sense as commandline arguments.

## Summary of the Pull Request

Fix the `TabTests`, and enable testing of types with XAML content. The `TabTests` were written many, many moons ago. they were intended to be our tests of XAML-like content within the Terminal app, so we could have unittests of Tabs, Panes, etc. Between their initial authoring and the day they were checked in, we had a bunch of build changes come in and break them irreperably. 

We've gotten them fixed now with _one weird trick_ <sup>doctors hate me</sup>. As long as there isn't an `App.xbf` in the test's output directory, then the tests will deploy just fine.

We also needed a bit of magic, cribbed straight from TAEF, to enable running test code synchronously on the UI thread. Hence, `CppwinrtTailored.h`.

<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
Every lambda capture in `Tab` and `TerminalPage` has been changed from capturing raw `this` to `std::weak_ptr<Tab>` or `winrt::weak_ref<TerminalPage>`. Lambda bodies have been changed to check the weak reference before use. 

Capturing raw `this` in `Tab`'s [title change event handler](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalApp/Tab.cpp#L299) was the root cause of #3776, and is fixed in this PR among other instance of raw `this` capture.

The lambda fixes to `TerminalPage` are unrelated to the core issue addressed in the PR checklist. Because I was already editing `TerminalPage`, figured I'd do a [weak_ref pass](https://github.com/microsoft/terminal/issues/3776#issuecomment-560575575).

## Detailed Description of the Pull Request / Additional comments
`Tab` now inherits from `enable_shared_from_this`, which enable accessing `Tab` objects as `std::weak_ptr<Tab>` objects. All instances of lambdas capturing `this` now capture `std::weak_ptr<Tab>` instead. `TerminalPage` is a WinRT type which supports `winrt::weak_ref<TerminalPage>`. All previous instance of `TerminalPage` lambdas capturing `this` has been replaced to capture `winrt::weak_ref<TerminalPage>`. These weak pointers/references can only be created after object construction necessitating for `Tab` a new function called after construction to bind lambdas.

Any anomalous crash related to the following functionality during closing a tab or WT may be fixed by this PR:
- Tab icon updating
- Tab text updating
- Tab dragging
- Clicking new tab button
- Changing active pane
- Closing an active tab
- Clicking on a tab
- Creating the new tab flyout menu

Sorry about all the commits. Will fix my fork after this PR! 😅

Anirudh Rayabharam f1ff0cf7ba Conhost: copy RTF to clipboard (#3595)
RTF data is now copied to the clipboard. The clipboard format name
used for RTF data is `Rich Text Format`.

Refactored some code in `Clipboard.cpp` so that the code for setting
data to the clipboard is re-used. Also, renamed parameter
`fAlsoCopyHtml` to `fAlsoCopyFormatting` to make it more generic.

Tested by copying text from console to WordPad. Also verified that
HTML copy is not regressed by copying to Word.

Closes #3560.
