## Detailed Description of the Pull Request / Additional comments

### Background
- We want the Terminal to be fast at drawing. To be fast at drawing, we perform differential drawing, or only drawing what is different from the previous frame. We use DXGI's `Present1` method to help us with this as it helps us compose only the deltas onto the previous frame at drawing time and assists us in scrolling regions from the previous frame without intervention. However, it only works on strictly integer pixel row heights.
- Most of the hit testing and size-calculation logic in both the `conhost` and the Terminal products are based on the size of an individual cell. Historically, a cell was always dictated in a `COORD` structure, or two `SHORT` values... which are integers. As such, when we specify the space for any individual glyph to be displayed inside our terminal drawing region, we want it to fall perfectly inside of an integer box to ensure all these other algorithms work correctly and continue to do so.
- Finally, we want the Terminal to have font fallback and locate glyphs that aren't in the primary selected font from any other font it can find on the system that contains the glyph, per DirectWrite's font fallback mechanisms. These glyphs won't necessarily have the same font or glyph metrics as the base font, but we need them to fit inside the same cell dimensions as if they did because the hit testing and other algorithms aren't aware of which particular font is sourcing each glyph, just the dimensions of the bounding box per cell.

### How does Terminal deal with this?
- When we select a font, we perform some calculations using the design metrics of the font and glyphs to determine how we could fit them inside a cell with integer dimensions. Our process here is that we take the requested font size (which is generally a proxy for height), find the matching glyph width for that height then round it to an integer. We back convert from that now integer width to a height value which is almost certainly now a floating point number. But because we need an integer box value, we add line padding above and below the glyphs to ensure that the height is an integer as well as the width. Finally, we don't add the padding strictly equally. We attempt to align the English baseline of the glyph box directly onto an integer pixel multiple so most characters sit crisply on a line when displayed. 
- Note that fonts and their glyphs have a prescribed baseline, line gap, and advance values. We use those as guidelines to get us started, but then to meet our requirements, we pad out from those. This results in fonts that should be properly authored showing gaps. It also results in fonts that are improperly authored looking even worse than they normally would.

### Now how does block and line drawing come in?
- Block and Line drawing glyphs are generally authored so they will look fine when the font and glyph metrics are followed exactly as prescribed by the font. (For some fonts, this still isn't true and we want them to look fine anyway.)
- When we add additional padding or rounding to make glyphs fit inside of a cell, we can be adding more space than was prescribed around these glyphs. This can cause a gap to be visible.
- Additionally, when we move things like baselines to land on a perfect integer pixel, we may be drawing a glyph lower in the bounding box than was prescribed originally.

### And how do we solve it?
- We identify all glyphs in the line and block drawing ranges.
- We find the bounding boxes of both the cell and the glyph.
- We compare the height of the glyph to the height of the cell to see if we need to scale. We prescribe a scale transform if the glyph wouldn't be tall enough to fit the box. (We leave it alone otherwise as some glyphs intentionally overscan the box and scaling them can cause banding effects.)
- We inspect the overhang/underhang above and below the boxes and translate transform them (slide them) so they cover the entire cell area.
- We repeat the previous two steps but in the horizontal direction.

Manually select a new tab when we're in fullscreen mode (#5809)
If we're fullscreen, the TabView isn't `Visible`. If it's not `Visible`,
it's _not_ going to raise a `SelectionChanged` event, which is what we
usually use to focus another tab. Instead, we'll have to do it manually
here.

So, what we're going to try to do is move the focus to the tab to the
left, within the bounds of how many tabs we have.

EX: we have 4 tabs: [A, B, C, D]. If we close:
* A (`tabIndex=0`): We'll want to focus tab B (now in index 0)
* B (`tabIndex=1`): We'll want to focus tab A (now in index 0)
* C (`tabIndex=2`): We'll want to focus tab B (now in index 1)
* D (`tabIndex=3`): We'll want to focus tab C (now in index 2)

`_UpdatedSelectedTab` will do the work of setting up the new tab as the
focused one, and unfocusing all the others.

Also, we need to _manually_ set the SelectedItem of the tabView here. If
we don't, then the TabView will technically not have a selected item at
all, which can make things like ClosePane not work correctly.

[Git2Git] Merged PR 4644345: conhost: disable the DX renderer in inbox builds

We're going to be taking on some changes to the Dx renderer that are at

inbox console. This commit removes support for the DX renderer from the
inbox console.

SizeBench reports that ConRenderDx contributes 55.1kb to the conhost
image (as its third largest constituent library), so this should net us
a couple pleasant WPG improvements down the line.

Don't set the new tab button colors for now (#5749)
This is actually related to another issue we have, #3917. I think if the system is set to "Dark" theme, but the app is set to light theme, then the brush lookup in `_ClearNewTabButtonColor` still returns to us the dark theme brushes.

Fortunately, since we're not actually setting the color of the new tab button anymore, we can just remove the call to that method now, and loop back on it later.

Make sure that EraseAll moves the Terminal viewport (#5683)
The Erase All VT sequence (`^[[2J`) is supposed to erase the entire
contents of the viewport. The way it usually does this is by shifting
the entirety of the viewport contents into scrollback, and starting the
new viewport below it. 

Currently, conpty doesn't propagate that state change correctly. When
conpty gets a 2J, it simply erases the content of the connected
terminal's viewport, by writing over it with spaces. Conpty didn't
really have a good way of communicating "your viewport should move", it
only knew "the buffer is now full of spaces".

This would lead to bugs like #2832, where pressing <kbd>ctrl+L</kbd> in
`bash` would delete the current contents of the viewport, instead of
moving the viewport down.

This PR makes sure that when conpty sees a 2J, it passes that through
directly to the connected terminal application as well. Fortunately, 2J
was already implemented in the Windows Terminal, so this actually fixes
the behavior of <kbd>ctrl+L</kbd>/`clear` in WSL in the Terminal.

## References

* #4252 - right now this isn't the _most_ optimal scenario, we're
  literally just printing a 2J, then we'll perform "erase line" `height`
  times. The erase line operations are all redundant at this point - the
  entire viewport is blank, but conpty doesn't really know that.
  Fortunately, #4252 was already filed for me to come through and
  optimize this path.

Add support for setting a tab's color at runtime w/ context menu (#3789)
This commit introduces a context menu for Tab and a new item,
"Color...", which will display a color picker.

A flyout menu, containing a custom flyout, is attached to each tab. The
flyout displays a palette of 16 preset colors and includes a color
picker. When the user selects or clears color, an event is fired, which
is intercepted by the tab to which the flyout belongs.

The changing of the color is achieved by putting the selected color in
the resource dictionary of the tab, using well-defined dictionary keys
(e.g. TabViewItemHeaderBackground). Afterwards the visual state of the
tab is toggled, so that the color change is visible immediately.

Custom-colored tabs will be desaturated (somewhat) by alpha blending
them with the tab bar background.

The flyout menu also contains a 'Close' flyout item.

## Validation Steps Performed
I've validated the behavior manually: start the program via the start
menu. Right click on the tab -> Choose a tab color.

The color flyout is going to be shown. Click a color swatch or click
'Select a custom color' to use the color picker. Use the 'Clear the
current color' to remove the custom color.

Closes #2994. References #3327.

Fix RTL regression (fixes #4779) (#5734)
<!-- 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
This fixes the RTL regression caused in #4747. We create the rectangle taking the direction (through the BiDi Level) into account, and then the rendering works again. The GlyphRun shaping could still probably use some work to be a polished thingy, and there are still issues with RTL getting chopped up a lot when there's font fallback going on, but this fixes the regression, and it's now functional again.

## Detailed Description of the Pull Request / Additional comments
The baseline is actually direction dependent. So when it was being initialized, the unconditional baseline as left broke it, setting the box off to right of the text. We just check if the `GlyphRun->bidiLevel` is set, and if so, we adjust it so that the baseline lines up with the right, not with the left.

Implement a pair of shims for cls, Clear-Host in conpty mode (#5627)
## Summary of the Pull Request

This PR implements a pair of shims for `cmd` and `powershell`, so that their `cls` and `Clear-Host` functions will clear the entire terminal buffer (like they do in conhost), instead of just the viewport. With the conpty viewport and buffer being the same size, there's effectively no way to know if an application is calling these API's in this way with the intention of clearing the buffer or the viewport. We absolutely have to guess. 

Each of these shims checks to see if the way that the API is being called exactly matches the way `cmd` or `powershell` would call these APIs. If it does, we manually write a `^[[3J` to the connected terminal, to get he Terminal to clear it's own scrollback.

~~_⚠️ If another application were trying to clear the **viewport** with an exactly similar API call, this would also cause the terminal scrollback to get cleared ⚠️_~~

* [x] Should these shims be restricted to when the process that's calling them is actually `cmd.exe` or `powershell.exe`? Can I even do this? I think we've done such a good job of isolating the client process information from the rest of the host code that I can't figure out how to do this.
  - YES, this can be done, and I did it.
* [ ] **TODO**: _While I'm here_, should I have `DoSrvPrivateEraseAll` (the implementation for `^[[2J`, in `getset.cpp`) also manually trigger a EraseAll in the terminal in conpty mode?

Intentionally leak our Application, so that we DON'T crash on exit (#5629)
We've got a weird crash that happens terribly inconsistently, but pretty
readily on migrie's laptop, only in Debug mode. Apparently, there's some
weird ref-counting magic that goes on during teardown, and our
Application doesn't get closed quite right, which can cause us to crash
into the debugger. This of course, only happens on exit, and happens
somewhere in the `...XamlHost.dll` code.

Crazily, if we _manually leak the `Application`_ here, then the crash
doesn't happen. This doesn't matter, because we really want the
Application to live for _the entire lifetime of the process_, so the only
time when this object would actually need to get cleaned up is _during
exit_. So we can safely leak this `Application` object, and have it just
get cleaned up normally when our process exits.

difficult for users who do not have access to the store to get our

Since these libraries can be redistributed, it's easiest if we simply
redistribute them.

Grab the write lock before updating the font (#5654)
## Summary of the Pull Request
Based on the discussion in #5479, it seems that the crash is caused by a race condition due to not obtaining the write lock before calling `TriggerFontChange`.

I'm not totally sure if my approach is the right one, but I've taken the lock out of `_RefreshSize` since it seems like all calls of `_RefreshSize` come after a `TriggerFontChange`/`UpdateFont`. Then I just 
made sure all calls of `TriggerFontChange`/`UpdateFont` are preceded with a `LockForWriting`.

If a class has a constructor which can be called with a single argument,
then this constructor becomes conversion constructor because such a
constructor allows conversion of the single argument to the class being

In some header files, there were constructors that took a value that
could involve implicit conversions, so I added explicit to ensure that
does not happen.

## Detailed Description of the Pull Request / Additional comments

Basically, during a resize, we try to restore the viewport position
correctly, and part of that checks where the current commandline ends.
However, when we do that, the commandline's _current_ state still
reflects the _old_ buffer size, so resizing to be smaller can cause us
to throw an exception, when we find that the commandline doesn't fit in
the new viewport cleanly.

By hiding it, then redrawing it, we avoid this problem entirely. We
don't need to perform the check on the old commandline contents (since
they'll be empty), and we'll redraw it just fine for the new buffer size

Clamp the new rows scrolling value to a positive number (#5630)

## Detailed Description of the Pull Request / Additional comments

The origin of this bug is that as newlines are emitted, we'll accumulate an enormous scroll delta into a selection region, to the point of overflowing a `SHORT`. When the overflow occurs, the `Terminal` would fail to send a `NotifyScroll()` to the `TermControl` hosting it.

For this bug to repro, we need to:
- Have a sufficiently large buffer, because each newline we'll accumulate a delta of (0, ~bufferHeight), so (bufferHeight^2 + bufferHeight) > SHRT_MAX
- Have a selection

Enforces a minimum width of 460 wide. This allows tabs to always be seen (albeit partially).

NOTE: A minimum height was originally added to allow the About menu to be seen. This minimum height was removed from this PR because we don't foresee a circumstance where your Terminal is in that state, and you can't just resize it to make the content fit properly.

Adjust TSFInputControl alignment (#5609)
This PR fixes a couple of issues with TSFInputControl alignment:

1. The emoji picker IME in particular would show up overlapping the
   current buffer row because I stupidly didn't realize that
   `TextBlock.ActualHeight` is 0 right after initialization and before
   it has any text. So, the emoji picker will show up on the bottom of
   the 0 height TextBlock, which overlaps the current buffer row. This
   isn't a problem with CJK because inputting text _causes_ the IME to
   show up, so by the time the IME shows up, the TextBlock has text and
   accordingly has a height.
2. It turns out the emoji picker IME doesn't follow the `TextBlock`
   bottom, unlike Chinese and Japanese IME, so if a user were to compose
   near the edge of the screen and let the `TextBlock` start line
   wrapping, the emoji IME doesn't follow the bottom of the `TextBlock`
   as it grows. This means that the `TextBlock` position doesn't update
   in the middle of composition, and the `LayoutRequested` event that it
   fires at the beginning of composition is the only chance we get to
   tell the emoji IME where to place itself. It turns out when we reset
   `TextBlock.Text`, the ActualHeight doesn't get immediately reset back
   to the min size. So if a user were to bring up the emoji IME before
   `ActualHeight` is reset, the IME will show up way below the current
   buffer row.
3. We don't currently `TryRedrawCanvas` when the window position changes
   (resizing, dragging the window around), so sometimes dragging or
   resizing the Terminal doesn't update the position of the IME. Ideally
   it should be listening to some "window position changed" event, but
   alas we don't have that and it would be much harder than this
   incoming fix. We'll just track the window bounds as part of
   `TryRedrawCanvas` and redraw if it changes. For the most part, this
   will allow the IME to update to where the new window position is, but
   it'll only be called if we receive a `LayoutRequested` event.

Replace the HRGN-based titlebar cutout with an overlay window (#5485)
Also known as "Kill HRGN II: Kills Regions Dead (#5485)"

Copying the description from @greg904 in #4778.

--- 8< ---
My understanding is that the XAML framework uses another way of getting
mouse input that doesn't work with `WM_SYSCOMMAND` with `SC_MOVE`. It
looks like it "steals" our mouse messages like `WM_LBUTTONDOWN`.

Before, we were cutting (with `HRGN`s) the drag bar part of the XAML
islands window in order to catch mouse messages and be able to implement
the drag bar that can move the window. However this "cut" doesn't only
apply to input (mouse messages) but also to the graphics so we had to
paint behind with the same color as the drag bar using GDI to hide the
fact that we were cutting the window.

The main issue with this is that we have to replicate exactly the
rendering on the XAML drag bar using GDI and this is bad because:
1. it's hard to keep track of the right color: if a dialog is open, it
   will cover the whole window including the drag bar with a transparent
   white layer and it's hard to keep track of those things.
2. we can't do acrylic with GDI

So I found another method, which is to instead put a "drag window"
exactly where the drag bar is, but on top of the XAML islands window (in
Z order). I've found that this lets us receive the `WM_LBUTTONDOWN`
messages.
--- >8 ---

Dustin's notes: I've based this on the implementation of the input sink
window in the UWP application frame host.

Tested manually in all configurations (debug, release) with snap,
drag, move, double-click and double-click on the resize handle. Tested
at 200% scale.

Lock when changing selection endpoint on wheel/auto-scroll (#5551)
Takes the lock inside two routines in `TermControl` that were changing
the selection endpoint while a rendering frame was still drawing,
resulting in several variants of graphical glitches from double-struck
selection boxes to duplicated line text.

## References

* [x] Manual tests passed since it's visual.
* [x] No extra doc besides the comments.
* [x] Am core contributor: Roar.

The renderer base and specific renderer engine do a lot of work to
remember the previous selection and compensate for scrolling regions and
deltas between frames. However, all that work doesn't quite match up
when the endpoints are changed out from under it. Unfortunately,
`TermControl` doesn't have a robust history of locking correctly in step
with the renderer nor does the renderer's `IRenderData` currently
provide any way of 'snapping' state at the beginning of a frame so it
could work without a full lock. So the solution for now is for the
methods that scroll the display in `TermControl` to take the lock that
is shared with the renderer's frame painter so they can't change out of
sync.

## Detailed Description of the Pull Request / Additional comments

Basically, if you use cleartype on a light background, what you'll get today is the text foreground color _added_ to the background. This will make the text look basically invisible. 

So, what I did was use some trickery with `PushLayer` to basically create a layer where the text would be forced to render in grayscale AA. I only enable this layer pushing business when both:
  * The user has enabled cleartype text
  * The background opacity < 1.0

This plumbs some information through from the TermControl to the DX Renderer to make this smooth.

## Validation Steps Performed

Opened both cleartype and grayscale panes SxS, and messed with the opacity liberally.

Include Cascadia Mono in-package, switch to it by default (#5505)
It was brought to our attention that shipping a font with ligatures as our default
font could be an accessibility issue for the visually-impaired. Unfortunately, we
don't have a renderer setting to disable ligatures (#759). Fortunately however, we
DO already have a version of Cascadia that doesn't have ligatures.

If we ship that and set it as our default font, we'll at least let people _opt_ to
have ligatures enabled by switching from `Cascadia Mono` to `Cascadia Code`.

Make sure background color is opaque when attrs are reversed (#5509)
In order to support a transparent background for the acrylic effect, the
renderer sets the alpha value to zero for the default background color.
However, when the _reversed video_ attribute is set, the background is
actually filled with the foreground color, and will not be displayed
correctly if it is made transparent. This PR addresses that issue by
making sure the rendered background color is opaque if the reversed
video attribute is set.

## References

* This is not a major issue at the moment, since the _reverse video_
  attribute is not typically forwarded though conpty, but that will
  change once #2661 is fixed.

## Detailed Description of the Pull Request / Additional comments

This simply adds an additional check in `Terminal::GetBackgroundColor`
to make sure the returned color is opaque if the _reverse video_
attribute is set. At some point in the future this check may need to be
extended to support the `DECSCNM` reverse screen mode, but for now
that's not an issue.

## Validation Steps Performed

I've run the test case from issue #5498, and confirmed that it now works
as expected. I've also got an experimental fix for #2661 that I've
tested with this patch, and that now displays _reverse video_ attributes
correctly too.

## Detailed Description of the Pull Request / Additional comments

**WAS:**
- We were using implicit DPI scaling on the `ID2D1RenderTarget` and running all of our processing in DIPs (Device-Independent Pixels). That's all well and good for getting things bootstrapped quickly, but it leaves the actual scaling of the draw commands up to the discretion of the rendering target.
- When we don't get to explicitly choose exactly how many pixels tall/wide and our X/Y placement perfectly, the nature of floating point multiplication and division required to do the presentation can cause us to drift off slightly out of our control depending on what the final display resolution actually is.
- Differential drawing cannot work unless we can know the exact integer pixels that need to be copied/moved/preserved/replaced between frames to give to the `IDXGISwapChain1::Present1` method. If things spill into fractional pixels or the sizes of rows/columns vary as they are rounded up and down implicitly, then we cannot do the differential rendering.

**NOW:**
- When deciding on a font, the `DxEngine` will take the scale factor into account and adjust the proposed height of the requested font. Then the remainder of the existing code that adjusts the baseline and integer-ifies each character cell will run naturally from there. That code already works correctly to align the height at normal DPI and scale out the font heights and advances to take an exact integer of pixels.
- `TermControl` has to use the scale now, in some places, and stop scaling in other places. This has to do with how the target's nature used to be implicit and is now explicit. For instance, determining where the cursor click hits must be scaled now. And determining the pixel size of the display canvas must no longer be scaled.
- `DxEngine` will no longer attempt to scale the invalid regions per my attempts in #5185 because the cell size is scaled. So it should work the same as at 96 DPI.
- The block is removed from the `DxEngine` that was causing a full invalidate on every frame at High DPI.
- A TODO was removed from `TermControl` that was invalidating everything when the DPI changed because the underlying renderer will already do that.
