## Summary of the Pull Request
Improve `ATTR_ROW::ReplaceAttrs` performance by only reserving the necessary capacity instead of resizing the new run.
That way `TextAttributeRun`s are only instantiated once instead of twice.

## Detailed Description of the Pull Request / Additional comments
Performance could be further improved by directly moving `TextAttributeRun`s into the new vector, but I considered this out of scope for this PR.
## Validation Steps Performed
CPU usage when running `cacafire` is slightly reduced.
## Summary of the Pull Request
This PR changes `TermControl::_KeyHandler` to use early returns, which you can think of as "guard clauses".
This has the benefit of a reduced nesting level, easier to understand control flow and opens op the way to more complex conditions.

## Summary of the Pull Request
Fixes#6377. `TerminalCore` does not initialize `_altGrAliasing`. The impact is minimized in WT because it defaults to `true` in higher layers. It's not initialized when WPF is driving.

Read the [JsonUtils Spec] for more details.
This pull request introduces the next version of JsonUtils. It is in a
separate file for ease of review and testing.
JsonUtilsNew will be renamed in a subsequent commit that rewrites our
JSON deserializers.
### Implementer's Notes
I went with telescoping exceptions for the key parsing code, because
it's totally possible that you can be five keys deep and encounter a
type error. This lets us encode information about all failures in the
chain instead of just the topmost one.
The original JsonUtilsNew code changed to use `decay` everywhere because
the tests wouldn't compile. We want to treat `GetValue<const guid>` _the
same as_ `GetValue<guid>`, and this lets us do so. `decay` is awesome.
I've been developing this with a shim that redirects `JsonUtils.h` to
`JsonUtilsNew.h`. I am not comfortable deleting the original until we've
moved off of it, and that _will_ be the subject of a followup PR.
## Validation Steps Performed
So many tests.

This commit reverts the removal of the "SSH hack" in #5383. It was
originally added as a solution to #4911, when we realized that SSH would
request the SS3 cursor key encoding but we weren't equipped to handle
it.
A number of folks have filed issues that, in summary, say "when I use
SSH, I can't select/copy/paste text". It turns out that SSH will _also_
pass through requests for mouse input. Terminal dutifully responds to
those requests, of course, by disabling mouse selection/copy/paste. SSH
is **NOT** actually in VT_INPUT_MODE, so it will never receive the mouse
messages.
It's important to note that even with #376 fixed, we are still required
to keep this check. With the closure of #376, we'll be able to convert
VT mouse input back into Win32 mouse input for Win32 applications . . .
but SSH also doesn't know how to handle Win32 mouse input.
Fixes#6476.
Fixes#6196.

In addition to the below (original) description, this commit introduces
a ThrottledFunc template that can throttle _any_ function. It applies
that type to muffle updates to the scrollbar.
---
Redo #3531 but without the bug that it caused (#3622) which is why it
was reverted.
I'm sorry if I explain this badly. If you don't understand a part, make
sure to let me know and I will explain it better.
### Explanation
How it worked before: `Terminal` signals that viewport changed ->
`TermControl::_TerminalScrollPositionChanged` gets called on the
terminal thread -> it dispatches work for later to be ran the UI thread
to updates the scrollbar's values
Why it's bad:
* If we have many viewport changes, it will create a long stack of
operations to run. Instead, we should just update the scroll bar with
the most recent information that we know.
* Imagine if the rate that the work gets pushed on the UI thread is
greater than the rate that it can handle: it might freeze?
* No need to be real time, we can wait just a little bit (8ms) to
accumulate viewport changes before we actually change the scroll bar's
value because it appears to be expensive (see perf below).
Now: `Terminal` signals that viewport changed ->
`TermControl::_TerminalScrollPositionChanged` gets called on the
terminal thread -> it tells the `ScrollBarUpdater` about a new update ->
the `ScrollBarUpdater` only runs one job (I don't know if that's the
right term) on the UI thread at a time. If a job is already running but
hasn't updated the scroll bar yet, it changes the setting in the already
existing job to update the scroll bar with the new values. A job "waits"
some time before doing the update to throttle updates because we don't
need real time scroll bar updates. -> eventually, it updates the scroll
bar If the user scrolls when a scroll bar update is pending, we keep the
scroll bar's Maximum and Minimum but let the user choose its new Value
with the `CancelPendingValueChange` method.
### Note
Also I changed a little bit the code from the Terminal to notify the
TermControl less often when possible.
I tried to scroll with the scroll bar, with the mouse wheel. I tried to
scroll while content is being outputted.
I tried to reproduce the crash from #2248 without success (good).

Closes#3622
For mysterious reasons lost to the sands of time, XAML will _never_ pass
us a VK_MENU event. This is something that'll probably get fixed in
WinUI 3, but considering we're stuck on system XAML for the time being,
the only way to work around this bug is to pass the event through
manually. This change generalizes the F7 handler into a "direct key
event" handler that uses the same focus and tunneling method to send
different key events, and then uses it to send VK_MENU.
## Validation Steps Performed
Opened the debug tap, verified that I was seeing alt key ups.
Also used some alt keybindings to make sure I didn't break them.
Closes#6421
## Summary of the Pull Request
This PR aims to move the command palette spec out of the draft state and into a finalized state for inclusion in the 2.0 version of the Windows Terminal.
Notably, I've added sections regarding the ability to run `wt` commandlines using the Command Palette UI, something we hadn't considered in the original draft, because `wt` commandlines didn't land for like _4 months_ after this first draft.

* [wpf] WM_KEYUP crashes on x64 #6444
- Turns out that doing the `(uint)lParam` cast worked fine for the
keydowns, because the value of lParam usually didn't have super
high-order bits set. That's not the case for keyups, where the 30th
bit is _always_ set. This is fixed by explicitly getting the byte
with the scancode in it.
* [wpf] WM_KEYUP generates wrong value in Win32 input mode #6445
- This was fixed by basically the same thing as the above.
* [wpf] WPF control crashes on startup trying to render cursor #6446
- This was a regression from #6337. I forgot to initialize the brush
used to paint the cursor, because the UWP version always uses color
(but the WPF one relies on the text foreground color).
* Also adds a minor change to the WPF test app, so that the user can
actually exit `win32-input-mode`.
* #6337 regressed #6446

## Detailed Description of the Pull Request / Additional comments
Two fixes:
1. For outputting lots of text, the base renderer class spent a lot of time allocating and freeing and reallocating the `Cluster` vector that adapts the text buffer information into render clusters. I've now cached this vector in the base render class itself and I shrink/grow it based on the viewport update that happens at the top of every frame. To prevent too much thrashing in the downward/shrink direction, I wrote the `til::manage_vector` helper that contains a threshold to only shrink if it asks for small enough of a size relative to the existing one. I used 80% of the existing size as the threshold for this one.
2. For outputting lots of changing colors, the VT graphics output engine spent a bunch of time allocating and reallocating the vector for `GraphicsOptions`. This one doesn't really have a predictable size, but I never expect it to get extremely big. So I just held it in the base class.

This pull request moves WindowUiaProvider back into Win32 interactivity
and deletes all mention of it from Windows Terminal. Terminal does not
have a single toplevel window that requires Console-like UIA, as each
Xaml control inside it is in charge of its own destiny.
I've also merged `IUiaWindow` and `IConsoleWindow` back together, as
well as `WindowUiaProviderBase` and `WindowUiaProvider`.
Things look a lot more like they did before we tore them apart.

* Tried to repro this in the Terminal, couldn't anymore.
When opening a new tab, it takes a few milliseconds before title to
appears. This PR makes it instantaneous.
* Updated the Terminal so that it can load the title from the settings
before it is initialized.
* Load terminal settings in TermControl constructor before the terminal
is initialized (see above).
* Update Tab so that it sets the TabViewItem's title in the constructor
(in Tab::_MakeTabViewItem) instead of waiting for the VT sequence to
set the title (from what I understand).
NOTE 1: there is a similar problem with the tabview icon which is not
fixed by this PR.
NOTE 2: This is only a problem with animations disabled because
otherwise the title fades in so there is enough time for it to be set
when it becomes visible.
## Validation
I ran the terminal and opened a new tab. The title appears instantly.
This commit introduces a new project that lets you F5 a working instance
of the Wpf Terminal Control.
To make the experience as seamless as possible, I've introduced another

requires (including itself) for "x64". This is the only way to ensure
that when you press F5, all of the native and managed dependencies get
updated.
It's all quite cool when it works.

Adds support for `win32-input-mode` to conhost, conpty, and the Windows
Terminal.
* The shared `terminalInput` class supports sending these sequences when
a VT client application requests this mode.
* ConPTY supports synthesizing `INPUT_RECORD`s from the input sent to it

* ConPTY requests this mode immediately on startup (if started with a
new flag, `PSEUDOCONSOLE_WIN32_INPUT_MODE`)
* The Terminal now supports sending this input as well, when conpty asks
for it.
Also adds a new ConPTY flag `PSEUDOCONSOLE_WIN32_INPUT_MODE` which
requests this functionality from conpty, and the Terminal requests this
by default.
Also adds `experimental.input.forceVT` as a global setting to let a user
opt-out of this behavior, if they don't want it / this ends up breaking
horribly.

Wildcards are not allowed in toplevel ItemGroups in vcxproj; they must
be generated by targets.
We mostly use wildcards for pulling in PRI files that are dumped on disk
by the translation tool. We don't want to check those in, so we can't
expand references to them.
To that end, I've introduced a new target that will take a list of
folders containing resw files and expand wildcards under them.
All[1] other wildcards have been moved into their respective targets
_or_ simply expanded.

CascadiaResources.build.items, so I haven't exploded it yet.
Fixes#6214.
This PR provides a faster algorithm for converting 8-bit and 24-bit
colors into the 4-bit legacy values that are required by the Win32
console APIs. It also fixes areas of the code that were incorrectly
using a simple 16-color conversion that didn't handle 8-bit and 24-bit
values.
The faster conversion algorithm should be an improvement for issues #783
and #3950.
One of the main points of this PR was to fix the
`ReadConsoleOutputAttribute` API, which was using a simplified legacy
color conversion (the original `TextAttribute:GetLegacyAttributes`
method), which could only handle values from the 16-color table. RGB
values, and colors from the 256-color table, would be mapped to
completely nonsensical values. This API has now been updated to use the
more correct `Settings::GenerateLegacyAttributes` method.
But there were also a couple of other places in the code that were using
`GetLegacyAttributes` when they really had no reason to be working with
legacy attributes at all. This could result in colors being downgraded
to 4-bit values (often badly, as explained above), when the code was
already perfectly capable of displaying the full 24-bits.
This included the fill colors in the IME composer (in `ConsoleImeInfo`),
and the construction of the highlighting colors in the color
search/selection handler (`Selection::_HandleColorSelection`). I also
got rid of some legacy attribute code in the `Popup` class, which was
originally intended to update colors below the popup when the settings
changed, but actually caused more problems than it solved.
The other major goal of this PR was to improve the performance of the
`GenerateLegacyAttributes` method, since the existing implementation
could be quite slow when dealing with RGB values.
The simple cases are handled much the same as they were before. For an
`IsDefault` color, we get the default index from the
`Settings::_wFillAttribute` field. For an `IsIndex16` color, the index
can just be returned as is.
For an `IsRgb` color, the RGB components are compressed down to 8 bits
(3 red, 3 green, 2 blue), simply by dropping the least significant bits.
This 8-bit value is then used to lookup a representative 16-color value
from a hard-coded table. An `IsIndex256` color is also converted with a
lookup table, just using the existing 8-bit index.
The RGB mapping table was calculated by taking each compressed 8-bit
color, and picking a entry from the _Campbell_ palette that best
approximated that color. This was done by looking at a range of 24-bit
colors that mapped to the 8-bit value, finding the best _Campbell_ match
for each of them (using a [CIEDE2000] color difference calculation), and
then the most common match became the index that the 8-bit value would
map to.
The 256-color table was just a simpler version of this process. For each
entry in the table, we take the default RGB palette value, and find it's
closest match in the _Campbell_ palette.
Because these tables are hard-coded, the results won't adjust to changes
in the palette. However, they should still produce reasonable results
for palettes that follow the standard ANSI color range. And since
they're only a very loose approximation of the colors anyway, the exact
value really isn't that important.
That said, I have tried to make sure that if you take an RGB value for a
particular index in a reasonable color scheme, then the legacy color
mapped from that value should ideally match the same index. This will
never be possible for all color schemes, but I have tweaked a few of the
table entries to improve the results for some of the common schemes.
One other point worth making regarding the hard-coded tables: even if we
wanted to take the active palette into account, that wouldn't actually
be possible over a conpty connection, because we can't easily know what
color scheme the client application is using. At least this way the
results in conhost are guaranteed to be the same as in the Windows
Terminal.
[CIEDE2000]: https://en.wikipedia.org/wiki/Color_difference#CIEDE2000
## Validation Steps Performed
This code still passes the `TextAttributeTests` that check the basic
`GetLegacyAttribute` behaviour and verify the all legacy attributes
roundtrip correctly. However, some of the values in the `RgbColorTests`
had to be updated, since we're now intentionally returning different
values as a result of the changes to the RGB conversion algorithm.
I haven't added additional unit tests, but I have done a lot of manual
testing to see how well the new algorithm works with a range of colors
and a variety of different color schemes. It's not perfect in every
situation, but I think it works well enough for the purpose it serves.
I've also confirmed that the issues reported in #5940 and #6247 are now
fixed by these changes.

In Windows, we build with /Zc:wchar_t- (which makes wchar_t an unsigned
short typedef.) This causes build breaks when we compare two wchar_t
values (or a wchar_t and an enum class that's of type wchar_t) and the
compiler decides that it might want to _promote them to TextAttribute_
before doing the comparison.

## Summary of the Pull Request
When we select a color for the tab, we update the foreground color of the text so that it maintains acceptable contrast with the new tab color. However, we weren't also updating the foreground color of the close button.
This is understandable though, because apparently this wasn't fixable until MUX 2.4 arrived. I'm not a XAML expert, but I know that setting this key only works when we're using MUX 2.4, so I'm assuming something about the TabView implementation changed in that release. _This PR is marked as a draft until #5778 is merged, then I'll re-target to master._
