- Fixes empty app title when `showTerminalTitleInTitlebar` is false
- Fixes Tab title propagation to Window title when
`showTerminalTitleInTitlebar` is false
- Fixes Tab title propagation to Window - title doesn't update when
Window is unfocused
1. There were a missing
`_settings.GlobalSettings().ShowTitleInTitlebar()` check. Because of
this Title update event was being fired even when
`showTerminalTitleInTitlebar` is false. This results in empty tab
title to propagate to Window title. Also then after switching tabs
back and forth, tab title propagates to window title. These shouldn't
propagate when `showTerminalTitleInTitlebar` is false. I added the
`showTerminalTitleInTitlebar` check in relevant logic to fix the
behavior.
2. Code was checking `tab.FocusState() != FocusState::Unfocused` , but
when the whole terminal window is not in focus, the active tab is
also in Unfocused state. This was preventing tab title to propagate
to window title when application is unfocused. I added the logic of
checking matching selected tabs' index. This fixes the issue.
## Validation Steps Performed
I did the reproduce steps descripted in the issue to reproduce the bugs.
After applying the fixes, the bugs don't appear anymore while doing the
reproduce steps.
Closes#8704
"disabledProfileSources" is saved to `CascadiaSettings` _not_
`GlobalAppSettings` (and, even then, it's only read when it's used,
never saved). This PR specifically detects if it was defined in
settings.json, and copies it over when the settings are serialized.
## Validation Steps Performed
1. Added "disabledProfileSources" to settings.json, then serialized. -->
"disabledProfileSources" is now maintained.
2. Updated `CascadiaSettings` serialization test
Closes#9032
## Summary of the Pull Request
Fix for #9021
Turns out that what was happening is that the _parent_ pane's `Closed` event was being caught by the tab, and parent panes always have `nullopt` as their id. So now the `Pane::Id()` call always returns an optional, allowing us to check if it has a value before we access it.

This adds the support for chaining OSC 10-12, allowing users to set all
of them at once.
**BREAKING CHANGE**
Before this PR, the OSC 10/11/12 command will only be dispatched iff the
first color is valid. This is no longer true. The new implementation
strictly follows xterm's behavior. Each color is treated independently.
For example, `\e]10;invalid;white\e\\` is effectively `\e]11;white\e\\`.

### Plurals and paste tenses
In the past, plurals `foo`+`s` and past tenses `foo`+`ed` were
automatically tolerated. This turned out to be a bad design choice on my
part.
The basic example is that `potatos` would sometimes be treated as a
mistake and sometimes not (depending on the presence of `potato`).
You can see in this PR, that this logic resulted in `Applys` being
accepted as a word along with `AppContainered` -- there's nothing
intrinsically wrong w/ the latter, but unfortunately in order to screen
out the former, my shortcut just couldn't stick around. This means that
the `dictionary`/`expect` files will grow perhaps by a tiny bit, but as
you can see, not really by much.
This is also why `thereses` (a user) was accepted as a word in the past
(therese is in the base dictionary, so `therese` + `s` was acceptable).
### Pull requests
When GitHub initially introduced GitHub Actions, the event for
`pull_request` was created without enough permission for a tool like
this to work properly. I worked around that by using the `schedule`
event. In 2020, they introduced a replacement event
`pull_request_target` which has enough permission. This means that I can
stop relying on the `schedule` event.
### Miscellaneous
* I've folded together some `expect/` files since now is as good a time
as any.
* I've included a hint about `excludes.txt` (I added a similar one for
our primary repo recently, and it came up this week in
`microsoft/terminal` -- @zadjii-msft)
* I've standardized on a default of `.github/actions/spelling` to make
the out of the box experience easier for new adopters, so I'm applying
that change here -- if you're attached to the old directory name,
specifying it is still supported. -- note the directory rename may
cause a merge conflict for people with open PRs and changes to the
contents, this shouldn't be a big problem.
The settings.json was not regenerated if WT was already open. This resulted in the `ShellExecute` from trying to open the settings to pop up Notepad and say that this file didn't exist. We now detect if the settings.json was deleted to kick off loading the settings.
Closes#8955
Pressing Ctrl+\ produces `^\` using the US keyboard layout, thanks to Ctrl-key mappings inside the keyboard layout, whereas some layouts, like the UK extended layout, don't contain those. This causes the character value to be zero and previously caused no VT sequence to be generated under these situations. This PR employs `MapVirtualKeyW` to infer the missing characters.
As a side effect this PR effectively causes _all_ major keys on the keyboard to produce Ctrl+combinations now.

## Detailed Description of the Pull Request / Additional comments
I added a private field to `DxEngine` to store the timestamp for when a custom shader is first loaded. The field is initialized in `_SetupTerminalEffects()`, and the calculated time value (seconds since the timestamp) passed to the actual shader is set in `_ComputePixelShaderSettings()`.
There remains an issue with with jerky animation due to the renderer not repainting when the window contents are not updated (see discussion in the original issue).
This is basically my first time writing C++; constructive review is enthusiastically welcomed 🙂
## Validation Steps Performed

## Validation Steps Performed
Ran the terminal with
```json
"schemes" :
[ {} ]
```
First the crash repro'd, now it doesn't.
If there is data being output when a tab is closed, that can sometimes
result in the application crashing, because the renderer may still be in
use at the time is it destroyed. This PR attempts to prevent that from
happening by adding a lock in the `TermControl::Close` method.
What we're trying to prevent is the connection thread still being
active, and potentially accessing the renderer, after it has been
destroyed. So by acquiring the terminal lock in `TermControl::Close`,
after we've stopped accepting new output, we can be sure that the
connection thread is no longer active (it holds the lock while it is
processing output). So once we've acquired and released the lock, it
should be safe to tear down and destroy the renderer.
## Validation Steps Performed
While this crash is difficult to reproduce in general usage, it occurred
quite frequently when testing my `DECPS` implementation (there is some
tricky thread synchronisation, which seems more likely to trigger the
issue). With this patch applied, though, those crashes have stopped
occurring.
I've also stepped through the shutdown code in the debugger, manually
freezing threads to get them aligned in the right way to trigger the
crash (as explained in issue #8734). Again with the patch applied, I can
no longer get the crash to occur.

This is an extension of #8885. A lot of users have grown accustomed to

close the Settings UI if we are in a `SettingsTab`.

Build and ran it fine. Changed TermControl, built and ran it fine. Now let's hope CI likes it.
This reverts the revert in #8838.
The problem was that the `Profile` in the singleton nav state would be
updated before the binding fired, so we'd end up modifying the _new_
profile, because both the old page and the new page would be pointing at
the _new_ profile already.
Instead of using a singleton instance of the profile nav state, we'll
create a new one each time. The new nav state attempt to steal the
selected pivot from the last instance of the nav state, if the profiles
are the same. This means that
This means that we won't end up modifying the new profile. The old
page's nav state will still have the old profile, so it'll still end up
modifying the old `ProfileViewModel`.

This PR adds support for the `DECID` (Identify Device) escape sequence,
which allows for querying the terminal type in a way that is backwards
compatible with VT52 terminals.
This simply checks for the `ESC Z` sequence in the `ActionEscDispatch`
method of output state machine, and forwards the query to the existing
`DeviceAttributes` dispatch method, since the expected response is
identical to a `DA` report.
## Validation Steps Performed
I've added an output engine test that verifies that the `ESC Z` sequence
is correctly interpreted as a `DA` query when in ANSI mode, and as a
VT52 identification query when in VT52 mode.

When we emit a BEL (visual or audible), show an indicator in the tab

## Detailed Description of the Pull Request / Additional comments
`Model::CascadiaSettings` was updated to have a `UpdateColorSchemeReferences()` function that updates all profiles referencing the newly renamed color scheme.
`Editor::ColorSchemesPageNavigationState` now takes and exposes a `Model::CascadiaSettings`.
When a color scheme is renamed or deleted, we use `CascadiaSettings` to update our list of color schemes appropriately, then call `UpdateColorSchemeReferences()` to update the profiles.
The tricky part is that `Profile` does not store a direct reference to `ColorScheme`, but rather the name of the color scheme. See [this tread](https://github.com/microsoft/terminal/issues/8756#issuecomment-760375027) for a discussion on this topic.

* We found and fixed this in November 2017, but I fumbled the replication and accidentally overwrote the commit. This digs it up from history and puts it back in our code.
* When the shortcut file cannot be read for whatever reason, we are setting the hotkey value to uninitialized data as we never initialize several members on the stack in this function. It just so happens that the one in the `dwHotkey` field is commonly `0x4c` or the letter `L` which is then sent into the window procedure to tell the OS to capture it as a global hotkey and foreground the `conhost.exe` that was started. We should realize the load failure and not set any hotkey at all and we should initialize the stack variables. This does both.

#8803 maintained a `ProfilePageNavigationState` in `MainPage` to remember
the pivot position. However, the two-way binding on the TextBoxes
now seem to happen too late (after the navigation occurs),
resulting in the text being applied to the wrong profile. In other
words, the sequence of events probably looks something like this:
1. user types text (_state.profile = old profile)
2. user moves to new profile
3. navigation completes (_state.profile = new profile)
4. textbox two-way binding fires, setting _state.profile.WHATEVER = value

Upon a settings reload, we would select the correct navigation item for
a profile, but navigate to the old one. As a result, you would navigate
to the old page that points to a dead profile object. This would make it
appear like you did not discard/save the changes.
This bugfix navigates to the newly created profile, ensuring that your
changes are actually applied to the settings model's clone in use.

Removes the visibility hack in `UpdateSettings` where we were hiding
Profile menu items instead of removing them. This hack was removed using
`ReplaceAll`. For an unknown reason, calling `Remove()` would result in
an out-of-bounds error in XAML code.
The "Discard" button would improperly refresh the Settings UI. Both of
the bugs were caused by holding a reference to a hidden menu item then
trying to set the `SelectedItem` to that menu item.
Additionally, 9283375 adds a check for the selected item in
`SettingsNav_ItemInvoked()`. This prevents navigation to an already
selected item. This was the heuristic used by the XAML Controls Gallery.

This PR adds a sample monarch/peasant application. This is a type of
application where a single "Monarch" can coordinate the actions of multiple
other "Peasant" processes, as described by the specs in #7240 and #8135.
This project is intended to be a standalone sample of how the architecture would
work, without involving the entirety of the Windows Terminal build. Eventually,
this architecture will be incorporated into `wt.exe` itself, to enable scenarios
like:
* Run `wt` in the current window (#4472)
* Single Instance Mode (#2227)
For an example of this sample running, see the below GIF:
This sample operates largely by printing to the console, to help the reader
understand how it's working through its logic.
I'm doing this mostly so we can have a _committed_ sample of this type of application, kinda like how VtPipeTerm is a sample ConPTY application. It's a lot easier to understand (& build on) when there aren't any window shenanigans, settings loading, Island instantiation, or anything else that the whole of `WindowsTerminal.exe` needs

This PR fixes two of the components of #8765.
> * [ ] Edit a color scheme -> Hit 'apply' -> the selected color scheme resets to the first color scheme in the list (instead of the one just edited)
This was fixed by storing the navigation state as a singleton in MainPage, and having the color schemes page update the selected scheme on that singleton. That way, a subsequent navigation to the schemes page could re-use the existing state.
> * [ ] The buttons turn gray on rollover covering up what color I'm looking at (I have dark mode)
This one was tricky. We're binding the resource for this button, to the color the button is bound to. We're also running a converter on that color, as to change the alpha slightly. This allows us to still have visual feedback on pointerover, without obscuring the color entirely.

`til::details::bitmap<Allocator>` will use `Allocator` for its
`dynamic_bitset`, and it will use a rebound allocator for its run storage.
Allocator should be an allocator type storing `unsigned long long`, the
backing store type for `dynamic_bitset`.
I've introduced a type alias, `til::bitmap`, which papers over the
allocator choice for all existing code. I've also introduced a second
type alias, `til::pmr::bitmap`, which lets a consumer use the C++
polymorphic allocator system.
I chatted with @miniksa about whether to keep the "full" allocator
version in `details` or not. We decided that for the simplicity of the
`til` namespace, we would. If anybody has a compelling reason to use
`til::details::bitmap<Allocator>` directly, we can re-evaluate this
decision.

## Detailed Description of the Pull Request / Additional comments
Currently the tab tool tip is the tab's title.
The PR teaches the TabBase to check if there is a switch to tab command
associated with the current tab index,
if so concatenates the the relevant mapping to the too tip.
Of course, prefers user defined bindings to the default ones.
Moved tool tip logic to TabBase so SettingsTab has tooltip as well.
The following code didn't previously work as the assignment operators
didn't return a self reference:

## Validation Steps Performed
Tested manually
This is by no means comprehensive. It will be unmarked as draft when it
is more comprehensive.
This pull request adds some tests for resizing a TextBuffer and
reflowing its contents. Each test takes the form of an initial state and
a number of buffers of different sizes. The initial state is used to
seed the first TextBuffer, and the subsequent buffers are only used to
compare.
I manually reimplemented some of the DBCS logic to ensure that the
buffers contain _exactly_ what they're supposed to. I know this is
non-ideal. After some of the CharRow changes in #8446 land, this will
need to be updated.
There's a cool bit of TAEF gore in here: the IDataSource. An IDataSource
allows us to programmatically return test cases. It's a code-only
version of its support for parameterized tests of the form `Data:x = {0,
1, 2}` .
The only downsides are...
1. It looks like COM (it is not using COM under the hood, just the COM
ABI)
2. Property values must be returned as strings.
To best support rich test types, I used IDataSource to produce _a lit of
array indices_ and nothing more. The test is run once for array member,
and it is the test's responsibility to look up the object to which that
index refers.
Works great though! Each reflow test is its own unit, and a failure in
an earlier reflow test will not tank a later one.

`winrt::Windows::Foundation::swap` (`C2665`). So instead, I did the
following approach:
- (unchanged) we're converting the `IMap` from EnumMappings into (1) a
map of localized strings and (2) the list for XAML controls
- instead of storing `EnumEntry`s to the `IObservableVector` directly,
store it to a `std::vector`
- sort the vector using `std::sort`
- _now_ initialize the `IObservableVector` using the sorted
`std::vector`
This uses the value of the associated enum to determine a sorting order.
Since we want the "negative" value (i.e. "none" or "hidden") to be last,
I use `EnumEntryComparator` and `EnumEntryReverseComparator` to
determine whether we want increasing or decreasing order respectively.
`INITIALIZE_BINDABLE_ENUM_SETTING_REVERSE_ORDER` is a copy of
`INITIALIZE_BINDABLE_ENUM_SETTING`, except it uses
`EnumEntryReverseComparator` to sort in decreasing order.
Closes#8758
Put some settings below the acrylic & background image settings. Those groups have controls that will become visible when the user enables the setting. If there's other controls below them, then it's less likely that the user has _exactly scrolled to the checkbox_. That means it's more likely that the newly visible controls will be on-screen.

Whenever you'd make a change to anything in the Terminal Control
project, then tried deploying the package, you'd get errors like
"Package contains two files with the same name and different content,
files are `Thing.xbf` and
`.../bin/x64/debug/TSM/TerminalControl/Thing.xbf`". It seems like
`GetPackagingOutputs` was double counting these xbfs as being both from
TerminalControl and also TSM&TSE. So if you'd change TerminalControl,
it'd change the xbf files, but not the ones in TSM/TSE, and then
eventually the wapproj would fail to put it all together.
This combination of flags seems to
* make mdmerge work
* make the packaging project work
* make a partial rebuild of TerminalControl followed by a deploy work
I'm hoping that this PR build will confirm that this works in CI as well.

## Detailed Description of the Pull Request / Additional comments
Bear with me, I wrote this before paternity leave, so code might be a bit stale.
Oddly, after startup, this _does not_ leave the focus on the pane you moved to. If you `move-focus` during startup, at the end of startup, we'll still focus a _random_ pane. This is because the terminal still auto-focus a TermControl when it's done with layout. While we'll maintain the active control just fine during the startup, at the end of startup, all the controls will complete layout in a random order.
This is no different than the startup right now. `wt sp ; sp ; sp` will focus a random pane at the end. This is left for a future someone to fix
This is also subject to #2398 / #4692. Moving in a direction isn't _totally_ reliable currently. `focus-pane -t ID` will certainly be more reliable, but this will work in the meantime?
## Validation Steps Performed
Opened probably 100 terminals, confirmed that the layout was always correct. Final focused pane was random, but the layout was right.

Basically, just impose a height on both the renamer box and the overall
tab header control. However, to ensure that the text in the tab renamer
box does not get clipped by its own border, we also need to set its font
size, which is slightly smaller than it was before but it _is_ the same
as the text block that it is trying to rename so I'd say its more
consistent now.
We also improve the tab renamer box so that it scrolls as more text is
added instead of getting truncated (when the tabWidthMode is anything
other than titleLength). When the tabWidthMode _is_ set to titleLength,
the renamer box can increase in length much more (see GIFs below).
Closes#8519
Following up https://github.com/microsoft/terminal/pull/8586 by @Hegunumo,
fully remove the command dispatching logic from Command Palette.
Currently Command Palette might dispatch command in Tab Switcher mode.
This leads to several inconsistencies:
* Only the commands with the same key modifier as an ATS anchor will be issued
* This command will not close the TabSwitcher
(while commands issued from TerminalPage do).
Implementation details:
* Pass KeyMapping rather than binding to CommandPalette
* Use this mapping inside previewKeyDownHandler of ATS to detect
if previous tab or next tab bindings were engaged.
No need to handle Ctrl+Tab explicitly anymore -
it is handled as any other binding.
* Cleanup the logic in TerminalPage::_SelectNextTab
that checks if CommandPalette is visible.
It is not required anymore, as visible palette would intercept the call.
* Remove dependency of TerminalPage on AppLogic
that was introduced lately .
Adds a `Microsoft.Terminal.Remoting.dll` to our solution. This DLL will
be responsible for all the Monarch/Peasant work that's been described in
#7240 & #8135.
This PR does _not_ implement the Monarch/Peasant architecture in any
significant way. The goal of this PR is to just to establish the project
layout, and the most basic connections. This should make reviewing the
actual meat of the implementation (in a later PR) easier. It will also
give us the opportunity to include some of the basic weird things we're
doing (with `CoRegisterClass`) in the Terminal _now_, and get them
selfhosted, before building on them too much.
This PR does have windows registering the `Monarch` class with COM. When
windows are created, they'll as the Monarch if they should create a new
window or not. In this PR, the Monarch will always reply "yes, please
make a new window".
Similar to other projects in our solution, we're adding 3 projects here:
* `Microsoft.Terminal.Remoting.lib`: the actual implementation, as a
static lib.
* `Microsoft.Terminal.Remoting.dll`: The implementation linked as a DLL,
for use in `WindowsTerminal.exe`.
* `Remoting.UnitTests.dll`: A unit test dll that links with the static
lib.
There are plenty of TODOs scattered about the code. Clearly, most of
this isn't implemented yet, but I do have more WIP branches. I'm using
[`projects/5`](https://github.com/microsoft/terminal/projects/5) as my
notation for TODOs that are too small for an issue, but are part of the
whole Process Model 2.0 work.

In dark mode (and high contrast mode), color animation of title bar
button uses wrong color. Cause of this issue is using invalid data in
`ColorAnimation`. I fixed this bug by changing `ColorAnimation` value
in XAML layout file.
According to a [forum post], `To` value of `ColorAnimation` must be
frozen. But original source code uses "color binding" which makes this
value dynamic. As a result, the value set by default is always used,
that means, light mode.
So I added new resource named `CaptionButtonStrokeColor` and
`CaptionButtonBackgroundColor` which has static color value.
In light mode and dark mode, I set `SystemBaseHighColor` in the color
resource. `SystemBaseHighColor` is the same as
`SystemControlForegroundBaseHighBrush.Color` which is originally used in
animation.
The background color animation happened to work correctly because its
value is the same between light mode and dark mode. But I also fixed
background color animation.
## Validation Steps Performed
There is no need to add new test with this fix.
- I changed the `theme` value in `settings.json` and confirmed that the
correct color values were used.
- I confirmed that it works correctly even if the Windows theme is
changed.

This commit makes "Open in Windows Terminal" Context menu work again for
directory background even on system that OS fix is not applied.
This is a fallback solution to OS fixes mentioned in #6414.
While OS fix is on its way, we need a fallback that works on existing OS
versions.
The approach to this is: when no item is selected (nullptr for
IShellItemArray*), we use shell api to query the path of current active
Explorer window. A special case is handled for Windows Desktop. Once
we are able to obtain the path, we launch Windows Terminal with it.
## Validation Steps Performed
1. Right click on desktop to bring up the Context menu, pick "Open in
Windows Terminal", verify that a terminal is opened with correct
initial path.
2. Open a few File Explorer windows, pick any window, navigate to a
folder, click on "Background" to bring up the context menu, click
"Open in Windows Terminal" verify that a terminal is opened with
correct initial path.

## Detailed Description of the Pull Request / Additional comments
* We found and fixed this in November 2017, but I fumbled the replication and accidentally overwrote the commit. This digs it up from history and puts it back in our code.
* When the shortcut file cannot be read for whatever reason, we are setting the hotkey value to uninitialized data as we never initialize several members on the stack in this function. It just so happens that the one in the `dwHotkey` field is commonly `0x4c` or the letter `L` which is then sent into the window procedure to tell the OS to capture it as a global hotkey and foreground the `conhost.exe` that was started. We should realize the load failure and not set any hotkey at all and we should initialize the stack variables. This does both.
## Validation Steps Performed

## Detailed Description of the Pull Request / Additional comments
- Sets up a PMR memory pool for the GDI Engine. It tends to alloc and free a bunch of little buffers during painting frames. The pool will likely hold onto that memory frame over frame, but we'd just be using it again and again and again anyway. So this way we avoid all the system memory allocator locks and syscalls.
## Validation Steps Performed
- Ran `big.txt` about 10x in the window. Checked WPR/WPA profile output before/after.
Make a few changes to memory usage throughout the application to reduce transient allocations from the `big.txt` test from ~213,000 to ~53,000.

## Detailed Description of the Pull Request / Additional comments
Transient allocations are those that are new'd, used, then delete'd. Going back and forth to the system allocator for things we're just going to throw away or use rapidly again is a performance detriment. Not only is it a bunch of time to go ask the system with a syscall, it also hits a whole bunch of locks on the allocators. This PR identifies a few places where we were accidentally allocating and didn't mean to or were allocating and freeing just to turn around and allocate again. I chose other strategies to avoid this.
## Validation Steps Performed
- Ran `big.txt` sample (~6MB file) before and after. Observed heap allocations with WPR.
Performs a number of minor bugfixes related to the Settings UI:
- b5370a1 Dropdown bug:
- the dropdown would display the keybinding for the first
`openSettings` found. So it would accidentally present and bind the
one for the Settings UI.
- 91eb49e autogenerated name for opening Settings UI:
- the Settings UI keybinding would display "open settings file". This
was updated to say "Open Settings UI".
- 1cadbf4 Profile Page navigation crash:
- the selected item off of a MUX navigation view returns a MUX
NavViewItem (as opposed to WUX)
- dd2f3e5 Hookup delete for Profile page navigation:
- missed a spot where we were manually navigating to the Profile
page. So it wasn't hooked up properly
- 9fea6de Properly cast NavViewItem tags
- When we update the NavigationView's menu items, we were casting the
tags to `Model::Profile` instead of `Editor::ProfileViewModel`.

Fixes the following bug:
> - [ ] JSON change --> crash
> - open SUI --> open JSON --> edit retro effects in JSON --> save file --> cry because the app crashed
## Additional comments
This was a part of some manual testing I performed on the Settings UI.
More intricate bugs are being reported on #6800 and will be fixed in
their own PR.
Fix `TabPaletteItem` to hold only a weak reference to a tab.
This way we guarantee that the refcount of the closed tab
gets to 0 immediately
(and that command palette cannot "raise it from the dead").
While this seems a correct thing to do,
it is still not clear why the `FilteredCommand` itself
(the one holding the `TabPaletteItem`) doesn't get released
until the UI is refreshed.
There is an impact of not registering to PropertyChanged event:
if the tab title changes during Tab Switcher navigation
the Tab Switcher item won't be updated immediately
(the change will apply next time the Tab Switcher is open).
Due to this change we need to make sure that the tabs binding
in https://github.com/microsoft/terminal/pull/8427
doesn't break the title / icon update.

* [x] Fixes leak found while bumbling around.
* [x] I work here.
## Detailed Description of the Pull Request / Additional comments
- We trace all the things leading up to the Action phase in the VT parser for ETW tracing to make debugging the parser easier, but we made two mistakes.
- At some point, three of the actions (related to print/execute) weren't dispatching the stored up sequence to tracing and not clearing it. So printing/executing in a giant run over and over caused the vector to bloat and bloat and bloat forever.
- We're storing things even when no one is listening. That's a waste.
## Validation Steps Performed
- Watched it grow every time I did `type big.txt` under `taskman.exe`. Then watched it not do that after.
- I did technically WPR it to figure out this was the culprit.
This PR adds support for the ANSI _italic_ graphic rendition attribute,
which is enabled by the `SGR 3` escape sequence.
For the GDI renderer, I've just created an additional italic variant of
the font, and then the `UpdateDrawingBrushes` method selects the
appropriate font variant into the device context based on the requested
text attributes.
It's a bit more complicated in the DX renderer, because we need both an
italic variant of the font, and a variant of the text format object. The
`CustomTextLayout` class also had to be updated to hold the two font and
format instances, and decide which of the variants to use based on a
`useItalicFont` property in the drawing context, initially set in the
`UpdateDrawingBrushes` method.
## Validation Steps Performed
I've created some test content using a range of different character sets
(e.g. CJK, block characters, emoji, etc.), then applied the italic
attribute mixed with various other SGR attributes to see how they
interact. The output isn't always perfect, but I think it seems
reasonable given the constraints of a cell-based terminal renderer.
Closes#5461
This commit introduces direct shortcut dispatch to TerminalPage, which
allows it to respond to key bindings before the command palette.
This allows the user to use shortcuts from the command palette while
it's open.
Closes#6679
Looks like recent regression:
1. Every time the tab gains focus (e.g., upon tab switching) we trigger `TaskbarProgressChanged`
2. This call results in `HideIcon` call
3. This call resets the value of Icon even if hide=false
4. This triggers reload of the image resulting in blinking
Introduces the following UI controls to the ColorSchemes page:
- "Add new" button
- next to dropdown selector
- adds a new color scheme named ("Color Scheme #" where # is the number of color schemes you have)
- "Rename" Button
- next to the selector
- replaces the ComboBox with a TextBox and the accept/cancel buttons appear
- "Delete" button
- bottom of the page
- opens flyout, when confirmed, deletes the current color scheme and selects another one
This also adds a Delete button to the Profiles page. The Hide checkbox was moved above the Delete button.

## Detailed Description of the Pull Request / Additional comments
**Color Schemes:**
- Deleting a color scheme selects another one from the list available
- Rename replaces the combobox with a textbox to allow editing
- The Add New button creates a new color scheme named "Color Scheme X" where X is the number of schemes defined
- In-box color schemes cannot be deleted
**Profile:**
- Deleting a profile selects another one from the list available
- the rename button does not exist (yet), because it needs a modification to the NavigationView's Header Template
- The delete button is disabled for in-box profiles (CMD and Windows Powershell) and dynamic profiles
## Validation Steps Performed
**Color Schemes - Add New**
✅ Creates a new color scheme named "Color Scheme X" (X being the number of color schemes)
✅ The new color scheme can be renamed/deleted/modified
**Color Schemes - Rename**
✅ You cannot rename an in-box color scheme
✅ The rename button has a tooltip
✅ Clicking the rename button replaces the combobox with a textbox
✅ Accept --> changes name
✅ Cancel --> does not change the name
✅ accepting/cancelling the rename operation updates the combo box appropriately
**Color Schemes - Delete**
✅ Clicking delete produces a flyout to confirm deletion
✅ Deleting a color scheme removes it from the list and select the one under it
✅ Deleting the last color scheme selects the last available color scheme after it's deleted
✅ In-box color schemes have the delete button disabled, and a disclaimer appears next to it
**Profile- Delete**
✅ Base layer presents a disclaimer at the top, and hides the delete button
✅ Dynamic and in-box profiles disable the delete button and show the appropriate disclaimer next to the disabled button
✅ Clicking delete produces a flyout to confirm deletion
✅ Regular profiles have a delete button that is styled appropriately
✅ Clicking the delete profile button opens a content dialog. Confirmation deletes the profile and navigates to the profile indexed under it (deleting the last one redirects to the last one)

I was looking at conhost/OpenConsole and noticed it was being pretty
inefficient with allocations due to some usages of std::deque and
std::vector that didn't need to be done quite that way.
So this uses std::vector for the TextBuffer's storage of ROW objects,
which allows one allocation to contiguously reserve space for all the
ROWs - on Desktop this is 9001 ROW objects which means it saves 9000
allocations that the std::deque would have done. Plus it has the
benefit of increasing locality of the ROW objects since deque is going
to chase pointers more often with its data structure.
Then, within each ROW there are CharRow and ATTR_ROW objects that use
std::vector today. This changes them to use Boost's small_vector, which
is a variation of vector that allows for the so-called "small string
optimization." Since we know the typical size of these vectors, we can
pre-reserve the right number of elements directly in the
CharRow/ATTR_ROW instances, avoiding any heap allocations at all for
constructing these objects.
There are a ton of variations on this "small_vector" concept out there
in the world - this one in Boost, LLVM has one called SmallVector,
Electronic Arts' STL has a small_vector, Facebook's folly library has
one...there are a silly number of these out there. But Boost seems like
it's by far the easiest to consume in terms of integration into this
repo, the CI/CD pipeline, licensing, and stuff like that, so I went with
the boost version.
In terms of numbers, I measured the startup path of OpenConsole.exe on
my dev box for Release x64 configuration. My box is an i7-6700k @ 4
Ghz, with 32 GB RAM, not that I think machine config matters much here:
| | Allocation count | Allocated bytes | CPU usage (ms) |
| ------ | ------------------- | ------------------ | -------------- |
| Before | 29,461 | 4,984,640 | 103 |
| After | 2,459 (-91%) | 4,853,931 (-2.6%) | 96 (-7%) |
Along the way, I also fixed a dynamic initializer I happened to spot in
the registry code, and updated some docs.

This commit adds a [progress ring] to the tab header when we receive an
OSC 9 sequence.
Adds an event handler in `Tab.cpp` for the event we raise when we get a
request to set the taskbar state/progress. This event handler updates
