## Summary of the Pull Request
In the original implementation, we used two different orderings for the color tables. The WT color table used ANSI order, while the conhost color table used a Windows-specific order. This PR standardizes on the ANSI color order everywhere, so the usage of indexed colors is consistent across both parts of the code base, which will hopefully allow more of the code to be shared one day.
## References
This is another small step towards de-duplicating `AdaptDispatch` and `TerminalDispatch` for issue #3849, and is essentially a followup to the SGR dispatch refactoring in PR #6728.

## Detailed Description of the Pull Request / Additional comments
Conhost still needs to deal with legacy attributes using Windows color order, so those values now need to be transposed to ANSI colors order when creating a `TextAttribute` object. This is done with a simple mapping table, which also handles the translation of the default color entries, so it's actually slightly faster than the original code.
And when converting `TextAttribute` values back to legacy console attributes, we were already using a mapping table to handle the narrowing of 256-color values down to 16 colors, so we just needed to adjust that table to account for the translation from ANSI to Windows, and then could make use of the same table for both 256-color and 16-color values.
There are also a few places in conhost that read from or write to the color tables, and those now need to transpose the index values. I've addressed this by creating separate `SetLegacyColorTableEntry` and `GetLegacyColorTableEntry` methods in the `Settings` class which take care of the mapping, so it's now clearer in which cases the code is dealing with legacy values, and which are ANSI values.
These methods are used in the `SetConsoleScreenBufferInfoEx` and `GetConsoleScreenBufferInfoEx` APIs, as well as a few place where color preferences are handled (the registry, shortcut links, and the properties dialog), none of which are particularly sensitive to performance. However, we also use the legacy table when looking up the default colors for rendering (which happens a lot), so I've refactored that code so the default color calculations now only occur once per frame.
The plus side of all of this is that the VT code doesn't need to do the index translation anymore, so we can finally get rid of all the calls to `XTermToWindowsIndex`, and we no longer need a separate color table initialization method for conhost, so I was able to merge a number of color initialization methods into one. We also no longer need to translate from legacy values to ANSI when generating VT sequences for conpty.
The one exception to that is the 16-color VT renderer, which uses the `TextColor::GetLegacyIndex` method to approximate 16-color equivalents for RGB and 256-color values. Since that method returns a legacy index, it still needs to be translated to ANSI before it can be used in a VT sequence. But this should be no worse than it was before.
One more special case is conhost's secret _Color Selection_ feature. That uses `Ctrl`+Number and `Alt`+Number key sequences to highlight parts of the buffer, and the mapping from number to color is based on the Windows color order. So that mapping now needs to be transposed, but that's also not performance sensitive.
The only thing that I haven't bothered to update is the trace logging code in the `Telemetry` class, which logs the first 16 entries in the color table. Those entries are now going to be in a different order, but I didn't think that would be of great concern to anyone.
## Validation Steps Performed
A lot of unit tests needed to be updated to use ANSI color constants when setting indexed colors, where before they might have been expecting values in Windows order. But this replaced a wild mix of different constants, sometimes having to use bit shifting, as well as values mapped with `XTermToWindowsIndex`, so I think the tests are a whole lot clearer now. Only a few cases have been left with literal numbers where that seemed more appropriate.
In addition to getting the unit tests working, I've also manually tested the behaviour of all the console APIs which I thought could be affected by these changes, and confirmed that they produced the same results in the new code as they did in the original implementation.
This includes:
- `WriteConsoleOutput`
- `ReadConsoleOutput`
- `SetConsoleTextAttribute` with `WriteConsoleOutputCharacter`
- `FillConsoleOutputAttribute` and `FillConsoleOutputCharacter`
- `ScrollConsoleScreenBuffer`
- `GetConsoleScreenBufferInfo`
- `GetConsoleScreenBufferInfoEx`
- `SetConsoleScreenBufferInfoEx`
I've also manually tested changing colors via the console properties menu, the registry, and shortcut links, including setting default colors and popup colors. And I've tested that the "Quirks Mode" is still working as expected in PowerShell.
In terms of performance, I wrote a little test app that filled a 80x9999 buffer with random color combinations using `WriteConsoleOutput`, which I figured was likely to be the most performance sensitive call, and I think it now actually performs slightly better than the original implementation.
I've also tested similar code - just filling the visible window - with SGR VT sequences of various types, and the performance seems about the same as it was before.

## Detailed Description of the Pull Request / Additional comments
### Window Title Generation
Every time the renderer checks the title, it's doing two bad things that
I've fixed:
1. It's assembling the prefix to the full title doing a concatenation.
No one ever gets just the prefix ever after it is set besides the
concat. So instead of storing prefix and the title, I store the
assembled prefix + title and the bare title.
2. A copy must be made because it was returning `std::wstring` instead
of `std::wstring&`. Now it returns the ref.
### Dirty Area Return
Every time the renderer checks the dirty area, which is sometimes
multiple times per pass (regular text printing, again for selection,
etc.), a vector is created off the heap to return the rectangles. The
consumers only ever iterate this data. Now we return a span over a
rectangle or rectangles that the engine must store itself.
1. For some renderers, it's always a constant 1 element. They update
that 1 element when dirty is queried and return it in the span with a
span size of 1.
2. For other renderers with more complex behavior, they're already
holding a cached vector of rectangles. Now it's effectively giving
out the ref to those in the span for iteration.
### Bitmap Runs
The `til::bitmap` used a `std::optional<std::vector<til::rectangle>>`
inside itself to cache its runs and would clear the optional when the
runs became invalidated. Unfortunately doing `.reset()` to clear the
optional will destroy the underlying vector and have it release its
memory. We know it's about to get reallocated again, so we're just going
to make it a `std::pmr::vector` and give it a memory pool.
The alternative solution here was to use a `bool` and
`std::vector<til::rectangle>` and just flag when the vector was invalid,
but that was honestly more code changes and I love excuses to try out
PMR now.
Also, instead of returning the ref to the vector... I'm just returning a
span now. Everyone just iterates it anyway, may as well not share the
implementation detail.
### UTF-8 conversions
When testing with Terminal and looking at the `conhost.exe`'s PTY
renderer, it spends a TON of allocation time on converting all the
UTF-16 stuff inside to UTF-8 before it sends it out the PTY. This was
because `ConvertToA` was allocating a string inside itself and returning
it just to have it freed after printing and looping back around again...
as a PTY does.
The change here is to use `til::u16u8` that accepts a buffer out
parameter so the caller can just hold onto it.
## Validation Steps Performed
- [x] `big.txt` in conhost.exe (GDI renderer)
- [x] `big.txt` in Terminal (DX, PTY renderer)
- [x] Ensure WDDM and BGFX build under Razzle with this change.
Many include statements use forward slashes, while others use backwards
slashes. This is inconsistent formatting. For this reason, I changed the
backward slashes to forward slashes since that is the standard.
This fixes a number of exceptions that can cause conhost to crash when
the buffer is resized in such a way that the viewport or cursor position
end up out of bounds.
Technically this is a fix for issue #256, although that has been closed
as "needs-repro".
The main fix was to add checks in the `SetConsoleScreenBufferSizeImpl`
and `SetConsoleScreenBufferInfoExImpl` methods, to make sure the
viewport doesn't extend past the bottom or right of the buffer after a
resize. If it has overflowed, we move the viewport back up or left until
it's back within the buffer boundaries. We also check if the cursor
position has ended up out of bounds, and if so, clamp it back inside the
buffer.
The `SCREEN_INFORMATION::SetViewport` was also a source of viewport
overflow problems, because it was mistakenly using inclusive coordinates
in its range checks, which resulted in them being off by one. That has
now been corrected to use exclusive coordinates.
Finally, the `IsCursorDoubleWidth` method was incorrectly marked as
`noexcept`, which was preventing its exceptions from being caught.
Ideally it shouldn't be throwing exceptions at all any more, but I've
removed the `noexcept` specifier, so if it does throw an exception,
it'll at least have more chance of recovering without a crash.
## Validation Steps Performed
I put together a few test cases (based on the reports in issues #276 and
#1976) which consistently caused conhost to crash, or to generate an
exception visible in the debug output. With this PR applied, those test
cases are no longer crashing or triggering exceptions.
Closes#1976
This pull request is the initial implementation of hyperlink auto
detection
Overall design:
- Upon startup, TerminalCore gives the TextBuffer some patterns it
should know about
- Whenever something in the viewport changes (i.e. text
output/scrolling), TerminalControl tells TerminalCore (through a
throttled function for performance) to retrieve the visible pattern
locations from the TextBuffer
- When the renderer encounters a region that is associated with a
pattern, it paints that region differently

This is a refactoring of the renderer color calculations to simplify the
implementation, and to make it easier to support additional
color-altering rendition attributes in the future (e.g. _faint_ and
_conceal_).
## References
* This is a followup to PRs #3817 and #6809, which introduced additional
complexity in the color calculations, and which suggested the need for
refactoring.
## Detailed Description of the Pull Request / Additional comments
When we added support for `DECSCNM`, that required the foreground and
background color lookup methods to be able to return the opposite of
what was requested when the reversed mode was set. That made those
methods unnecessarily complicated, and I thought we could simplify them
considerably just by combining the calculations into a single method
that derived both colors at the same time.
And since both conhost and Windows Terminal needed to perform the same
calculations, it also made sense to move that functionality into the
`TextAttribute` class, where it could easily be shared.
In general this way of doing things is a bit more efficient. However, it
does result in some unnecessary work when only one of the colors is
required, as is the case for the gridline painter. So to make that less
of an issue, I've reordered the gridline code a bit so it at least
avoids looking up the colors when no gridlines are needed.
## Validation Steps Performed
Because of the API changes, quite a lot of the unit tests had to be
updated. For example instead of verifying colors with two separate calls
to `LookupForegroundColor` and `LookupBackgroundColor`, that's now
achieved with a single `LookupAttributeColors` call, comparing against a
pair of values. The specifics of the tests haven't changed though, and
they're all still working as expected.
I've also manually confirmed that the various color sequences and
rendition attributes are rendering correctly with the new refactoring.

## Summary of the Pull Request
Block selections were always read and displayed as line selections in UIA. This fixes that.
## PR Checklist

## Detailed Description of the Pull Request / Additional comments
1. Expose `IsBlockSelection()` via IUiaData
2. Update the constructor to be able to take in a block selection parameter
3. Make ScreenInfoUiaProviders pass step 1 output into step 2 constructor
4. Update all instances of `UiaTextRange::GetTextRects()` to include this new flag
## Validation Steps Performed
Manually tested.
Additional tests would be redundant as GetTextRects() is tested in the text buffer.
cmatrix is somewhat of a pathological case for our infrastructure: it
prints out a bunch of green and white characters and then updates them a
million times a second.
It also maintains a column of space between every green character. When
it prints this column, it prints it in "default" or "white". This ends
up making runs of text that look like this:
(def: G=green B=bright white W=white *=matrix char =space)
G W G W G W G W G W G W G W G W
G W G W G W G W G W G W G W G W

Every one of those color transitions causes us to break up the run of
text and start rendering it again. This impacts GDI, Direct2D *and*
ConPTY. In the example above, there are 120 runs.
The problem is, printing a space doesn't **use** the foreground color!
This commit introduces an optimization. When we're about to break a text
cluster because its attributes changed, we make sure that it's not just
filled with spaces and doesn't differ in any visually-meaningful way
(like underline or strikethrough, considering global invert state).
This lets us optimize both the rendering _and_ the PTY output to look
like this:
G* * * * * * * B*G
G* * * * * * *
G* * * B*G * * *
G* B*G * * * * *
G* * * B*G * *
B*G * * B*G *
G * * B*G
G B*G *
Text will be printed at best line-by-line and at worst only when the
visible properties of the screen actually change. In the example
above, there are only 21 runs.
This speeds up cmatrix remarkably.

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 😀

## 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.

## 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.
## Summary of the Pull Request
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.
Additionally, I moved all TriggerSelection() calls to the renderer from Terminal to TermControl for consistency. This ensures we only call it _once_ when we make a change to our selection state.

Refactors the accessibility providers (ScreenInfoUiaProvider and UiaTextRange) into a better separated model between ConHost and Windows Terminal.
ScreenInfoUiaProviderBase and UiaTextRangeBase are introduced. ConHost and Windows Terminal implement their own versions of ScreenInfoUiaProvider and UiaTextRange that inherit from their respective base classes.
WindowsTerminal's ScreenInfoUiaProvider --> TermControlUiaProvider
**The Basics of Accessibility**
- [What is a User Interaction Automation (UIA) Tree?](https://docs.microsoft.com/en-us/dotnet/framework/ui-automation/ui-automation-tree-overview)
- Other projects (i.e.: Narrator) can take advantage of this UIA tree and are used to present information within it.
- Some things like XAML already have a UIA Tree. So some UIA tree navigation and features are already there. It's just a matter of getting them hooked up and looking right.
**Accessibility in our Project**
There's a few important classes...
regarding Accessibility...
- **WindowUiaProvider**: This sets up the UIA tree for a window. So this is the top-level for the UIA tree.
- **ScreenInfoUiaProvider**: This sets up the UIA tree for a terminal buffer.
- **UiaTextRange**: This is essential to interacting with the UIA tree for the terminal buffer. Actually gets portions of the buffer and presents them.
regarding the Windows Terminal window...
- **BaseWindow**: The foundation to a window. Deals with HWNDs and that kind of stuff.
- **IslandWindow**: This extends `BaseWindow` and is actually what holds our Windows Terminal
- **NonClientIslandWindow**: An extension of the `IslandWindow`
regarding ConHost...
- **IConsoleWindow**: This is an interface for the console window.
- **Window**: This is the actual window for ConHost. Extends `IConsoleWindow`
- `IConsoleWindow` changes:
- move into `Microsoft::Console::Types` (a shared space)
- Have `IslandWindow` extend it
- `WindowUiaProvider` changes:
- move into `Microsoft::Console::Types` (a shared space)
- Hook up `WindowUiaProvider` to IslandWindow (yay! we now have a tree)
### Changes to the WindowUiaProvider
As mentioned earlier, the WindowUiaProvider is the top-level UIA provider for our projects. To reuse as much code as possible, I created `Microsoft::Console::Types::WindowUiaProviderBase`. Any existing functions that reference a `ScreenInfoUiaProvider` were virtual-ized.
In each project, a `WindowUiaProvider : WindowUiaProviderBase` was created to define those virtual functions. Note that that will be the main difference between ConHost and Windows Terminal moving forward: how many TextBuffers are on the screen.
So, ConHost should be the same as before, with only one `ScreenInfoUiaProvider`, whereas Windows Terminal needs to (1) update which one is on the screen and (2) may have multiple on the screen.
🚨 Windows Terminal doesn't have the `ScreenInfoUiaProvider` hooked up yet. We'll have all the XAML elements in the UIA tree. But, since `TermControl` is a custom XAML Control, I need to hook up the `ScreenInfoUiaProvider` to it. This work will be done in a new PR and resolve GitHub Issue #1352.
### Moved to `Microsoft::Console::Types`
These files got moved to a shared area so that they can be used by both ConHost and Windows Terminal.
This means that any references to the `ServiceLocator` had to be removed.
- `IConsoleWindow`
- Windows Terminal: `IslandWindow : IConsoleWindow`
- `ScreenInfoUiaProvider`
- all references to `ServiceLocator` and `SCREEN_INFORMATION` were removed. `IRenderData` was used to accomplish this. Refer to next section for more details.
- `UiaTextRange`
- all references to `ServiceLocator` and `SCREEN_INFORMATION` were removed. `IRenderData` was used to accomplish this. Refer to next section for more details.
- since most of the functions were `static`, that means that an `IRenderData` had to be added into most of them.
### Changes to IRenderData
Since `IRenderData` is now being used to abstract out `ServiceLocator` and `SCREEN_INFORMATION`, I had to add a few functions here:
- `bool IsAreaSelected()`
- `void ClearSelection()`
- `void SelectNewRegion(...)`
- `HRESULT SearchForText(...)`
`SearchForText()` is a problem here. The overall new design is great! But Windows Terminal doesn't have a way to search for text in the buffer yet, whereas ConHost does. So I'm punting on this issue for now. It looks nasty, but just look at all the other pretty things here. :)
