## 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.

## 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

## Summary of the Pull Request
The original PR had a few TODOs in it without issue numbers. IMO, this wasn't important enough to block the PR over. _Also I'm impatient and wanted that setting_.
After I merged the PR I created the issues and added the numbers myself.

Really none, I just built it and :fingers_crossed:
This PR creates a Universal entrypoint for the Windows Terminal solution
in search of our goals to run everywhere, on all Windows platforms.
The Universal entrypoint is relatively straightforward and mostly just
invokes the App without any of the other islands and win32 boilerplate
required for the centennial route. The Universal project is also its own
packaging project all in one and will emit a relevant APPX.
A few things were required to make this work correctly:
* Vcxitems reuse of resources (and link instructions on all of them
for proper pkg layout)
* Move all Terminal project CRT usages to the app ones (and ensure
forwarders are only Nugetted to the Centennial package to not pollute
the Universal one)
* Fix/delay dependencies in `TerminalApp` that are not available in
the core platform (or don't have an appropriate existing platform
forwarder... do a loader snaps check)
* vcpkg needs updating for the Azure connection parser
* font fallbacks because Consolas isn't necessarily there
* fallbacks because there are environments without a window handle
Some of those happened in other small PRs in the past week or two. They
were relevant to this.
Note, this isn't *useful* as such yet. You can run the Terminal in this
context and even get some of the shells to work. But they don't do a
whole lot yet. Scoping which shells appear in the profiles list and only
offering those that contextually make sense is future work.
* Break everything out of App except the base initialization for XAML. AppLogic is the new home.
* deduplicate logics by always using the app one (since it has to be there to support universal launch).
* apparently that was too many cross-boundary calls and we can cache it because winrt objects are magic.
* Put UWP project into solution.
* tabs in titlebar needs disabling from uwp context as the non-client is way different. This adds a method to signal that to logic and apply the setting override.
* Change to use App CRT in preparation for universal.
* Try to make project build again by setting winconpty to static lib so it'll use the CRT inside TerminalConnection (or its other consumers) instead of linking its own.
* Remove test for conpty dll, it's a lib now. Add additional commentary on how CRT linking works for future reference. I'm sure this will come up again.
* This fixes the build error.
* use the _apiset variant until proven otherwise to match the existing one.
* Merge branch 'master' into dev/miniksa/uwp3
* recorrect spacing in cppwinrt.build.pre.props
* Add multiple additional fonts to fallback to. Also, guard for invalid window handle on title update.
* Remove ARMs from solution.
* Share items resources between centennial and universal project.
* cleanup resources and split manifest for dev/release builds.
* Rev entire solution to latest Toolkit (6.0.0 stable release).
* shorten the items file using include patterns
* cleanup this filters file a bit.
* Fix C26445 by using string_view as value, not ref. Don't build Universal in Audit because we're not auditing app yet.
* some PR feedback. document losing the pointer. get rid of 16.3.9 workarounds. improve consistency of variable decl in applogic.h
* Make dev phone product ID not match prod phone ID. Fix universal package identity to match proposed license information.

## Summary of the Pull Request
This introduces a setting to both Profiles and ColorSchemes called <code>selectionBackground</code> that allows you to change the selection background color to what's specified. If <code>selectionBackground</code> isn't set in either the profile or color scheme, it'll default to what it was before - white.

We now truncate the font name as it goes out to GDI APIs, in console API
servicing, and in the propsheet.
I attempted to defer truncating the font to as far up the stack as
possible, so as to make FontInfo usable for the broadest set of cases.
There were a couple questions that came up: I know that `Settings` gets
memset (memsat?) by the registry deserializer, and perhaps that's
another place for us to tackle. Right now, this pull request enables
fonts whose names are >= 32 characters _in Windows Terminal only_, but
the underpinnings are there for conhost as well. We'd need to explicitly
break at the API, or perhaps return a failure or log something to
telemetry.
* Should we log truncation at the API boundary to telemetry?
-> Later; followup filed (#3123)
* Should we fix Settings here, or later?
-> Later; followup filed (#3123)
* `TrueTypeFontList` is built out of things in winconp, the private
console header. Concern about interop structures.
-> Not used for interop, followup filed to clean it up (#3123)
* Is `unsigned int` right for codepage? For width?
-> Yes: codepage became UINT (from WORD) when we moved from Win16 to
Win32
This commit also includes a workaround for #3170. Growing
CONSOLE_INFORMATION made us lose the struct layout lottery during
release builds, and this was an expedient fix.
Closes#602.
Related to #3123.
This adds the WPF control to our project, courtesy of the Visual Studio team.
It re-hosts the Terminal Control components inside a reusable WPF adapter so it can be composed onto C# type surfaces like Visual Studio requires.
## Summary of the Pull Request
Adds support for Italics, Blinking, Invisible, CrossedOut text, THROUGH CONPTY. This does **NOT** add support for those styles to conhost or the terminal.
We will store these "Extended Text Attributes" in a `TextAttribute`. When we go to render a line, we'll see if the state has changed from our previous state, and if so, we'll appropriately toggle that state with VT. Boldness has been moved from a `bool` to a single bit in these flags.
Technically, now that these are stored in the buffer, we only need to make changes to the renderers to be able to support them. That's not being done as a part of this PR however.

If _PaintFrameForEngine returns E_PENDING, we'll give it another two
tries to get itself straight. If it continues to fail, we'll take down
the application.
We observed that the DX renderer was failing to present the swap chain
and failfast'ing when it did so; however, there are some errors from
which DXGI guidance suggests we try to recover. We'll now return
E_PENDING (and destroy our device resources) when we hit those errors.
Fixes#2265.
Since we're rendering with antialiasing enabled, we need to make sure
we're stroking actual pixels; to do that, we need to adjust all of our
coordinates by the StrokeWidth / 2. We're always using a stroke width of
1, so that means 0.5.
While I was here, I took the opportunity to fix the color of the grid
lines. Fixes#543.
* Stop the crash with fonts by trying a few fallback/backup fonts if we can't find what was selected.
* Create fallback pattern for finding a font. Resolve and pass the locale name. Retrieve the font name while retrieving the font object. Use retrieved data in the _GetProposedFont methods instead of re-resolving it.
* Add details to schema about fallback. Finish comment explaining fallback pattern to doc comment on method.
* If IDWriteTextFormat1 does not exist, return directly
* We use DXGI_SCALING_NONE create SwapChain first, if failed switch to DXGI_SCALING_STRETCH

Certain DirectX features are unavailable on windows 7. The important ones as they are used in the DX renderer are color font rendering and fallback font support. Color fonts did not exist at all on windows 7 so running basic glyphrun rendering should work just fine.
Fallback font support was not exposed to the user in windows 7, making dealing with them difficult. Rather than try to get some workarounds to properly enable it I have opted to just conditionally disable the support on windows 7.
This commit enables a software rendering fallback for the DX renderer in the case that hardware acceleration fails. This is primarily useful for Hyper-V environments where hardware acceleration is not guaranteed to exist.
This will be useful for future work to enable the DX renderer to run on windows 7 since win7 virtual machines do not/cannot have hardware acceleration unlike windows 10 machines
This commit does two things:
- Fallback to `D3D_DRIVER_TYPE_WARP` if `D3D_DRIVER_TYPE_HARDWARE` fails.
- pass `NULL` as the adapter instead of creating the default adapter ourselves.
This encompasses a handful of problems with column counting.
The Terminal project didn't set a fallback column counter. Oops. I've fixed this to use the `DxEngine` as the fallback.
The `DxEngine` didn't implement its fallback method. Oops. I've fixed this to use the `CustomTextLayout` to figure out the advances based on the same font and fallback pattern as the real final layout, just without "rounding" it into cells yet.
- `CustomTextLayout` has been updated to move the advance-correction into a separate phase from glyph shaping. Previously, we corrected the advances to nice round cell counts during shaping, which is fine for drawing, but hard for column count analysis.
- Now that there are separate phases, an `Analyze` method was added to the `CustomTextLayout` which just performs the text analysis steps and the glyph shaping, but no advance correction to column boundaries nor actual drawing.
I've taken the caching code that I was working on to improve chafa, and I've brought it into this. Now that we're doing a lot of fallback and heavy lifting in terms of analysis via the layout, we should cache the results until the font changes.
I've adjusted how column counting is done overall. It's always been in these phases:
1. We used a quick-lookup of ranges of characters we knew to rapidly decide `Narrow`, `Wide` or `Invalid` (a.k.a. "I dunno")
2. If it was `Invalid`, we consulted a table based off of the Unicode standard that has either `Narrow`, `Wide`, or `Ambiguous` as a result.
3. If it's still `Ambiguous`, we consult a render engine fallback (usually GDI or now DX) to see how many columns it would take.
4. If we still don't know, then it's `Wide` to be safe.
- I've added an additional flow here. The quick-lookup can now return `Ambiguous` off the bat for some glyph characters in the x2000-x3000 range that used to just be simple shapes but have been retroactively recategorized as emoji and are frequently now using full width color glyphs.
- This new state causes the lookup to go immediately to the render engine if it is available instead of consulting the Unicode standard table first because the half/fullwidth table doesn't appear to have been updated for this nuance to reclass these characters as ambiguous, but we'd like to keep that table as a "generated from the spec" sort of table and keep our exceptions in the "quick lookup" function.
I have confirmed the following things "just work" now:
- The windows logo flag from the demo. (⚫⚪💖✅🌌😊)
- The dotted chart on the side of crossterm demo (•)
- The powerline characters that make arrows with the Consolas patched font (██)
- An accented é
- The warning and checkmark symbols appearing same size as the X. (✔⚠🔥)
