8f346a7158 Rewrite Utf16Parser (#14417)
This commit replaces `Utf16Parser` with `<til/unicode.h>` which includes:
* `til::utf16_iterator` as a replacement for `Utf16Parser::Parse`
* `til::utf16_next` as a replacement for `Utf16Parser::ParseNext`

This fixes 2 bugs with `Utf16Parser`:
* Swallowing invalid surrogate pairs instead of turning them into U+FFFD.
* `std::vector<std::vector<wchar_t>>`. It's now >12000% faster.

## Validation Steps Performed
* New unit tests pass 
* Searching for narrow/wide characters in conhost works

c51bb3a7a6 Add support for fractional font sizes (#14013)
After this commit a user may specify fractional font sizes.
Support was only implemented for AtlasEngine however.
DxEngine continues to use rounded (integer) font sizes.

Closes #6678

## Validation Steps Performed
* Install a bitmap font that requires fractional font sizes
  (e.g. Terminus TTF, https://files.ax86.net/terminus-ttf/)
* Set font size to something integer (e.g. 14pt)
  Glyphs are blurry 
* Set font size to something fractional (e.g. 13.5pt)
  Glyphs are crisp

2cd2351deb Miscellaneous bug fixes for Mark Mode (#13358)
## Summary of the Pull Request
1. [copy on select] when manually copying text (i.e. kbd or right-click) while in mark/quick-edit mode, we now dismiss the selection.
2. `Enter` is now bound to copy by default. 
    - This works very well with mark mode and provides a more consistent behavior with conhost's selection experience overall.
    - "why not hardcode `Enter` as a way to copy when in mark mode?"
        - In an effort to make this as configurable as possible, I decided to make it a configurable keybinding, but am open to suggestions.
3. selection markers
   a. we now hide the selection markers when multi-clicking the terminal.
   b. selection markers are now properly shown when a single cell selection exists
      - Prior to this PR, any single cell selection would display both markers. Now, we actually track which endpoint we're moving and display the appropriate one.
4. ensures that when you use keyboard selection to move past the top/bottom of the scroll area, we clamp it to the origin/bottom-right respectively. The fix is also better here in that it provides consistent behavior across all of the `_MoveByX` functions.
5. adds `toggleBlockSelection` to the schema

#13053 

## Validation Steps Performed
Did a whole flowchart of expected behavior with copy on select:
- enable `copyOnSelect`
   - make a selection with the mouse
      -  right-click should copy the text --> clear the selection --> paste
   - use keyboard selection to quick-edit the existing selection
      -  `copy` action should clear the selection
      -  right-click should copy the text --> clear the selection --> paste

Played with selection markers a bit in mark mode and quick edit mode. Markers are updating appropriately.

ed27737233 Use 32-bit coordinates throughout the project (#13025)
Previously this project used a great variety of types to present text buffer
coordinates: `short`, `unsigned short`, `int`, `unsigned int`, `size_t`,
`ptrdiff_t`, `COORD`/`SMALL_RECT` (aka `short`), and more.
This massive commit migrates almost all use of those types over to the
centralized types `til::point`/`size`/`rect`/`inclusive_rect` and their
underlying type `til::CoordType` (aka `int32_t`).

Due to the size of the changeset and statistics I expect it to contain bugs.
The biggest risk I see is that some code potentially, maybe implicitly, expected
arithmetic to be mod 2^16 and that this code now allows it to be mod 2^32.
Any narrowing into `short` later on would then throw exceptions.

57c3953aca Use type inference throughout the project (#12975)
#4015 requires sweeping changes in order to allow a migration of our buffer
coordinates from `int16_t` to `int32_t`. This commit reduces the size of
future commits by using type inference wherever possible, dropping the
need to manually adjust types throughout the project later.

As an added bonus this commit standardizes the alignment of cv qualifiers
to be always left of the type (e.g. `const T&` instead of `T const&`).

The migration to type inference with `auto` was mostly done
using JetBrains Resharper with some manual intervention and the
standardization of cv qualifier alignment using clang-format 14.

a496af3614 Allow windows created by console apps to appear above the Terminal (#12799)
## Window shenanigans, part the third:

Hooks the Terminal's focus state up to the underlying ConPTY. This is LOAD BEARING for allowing windows created by console applications to bring themselves to the foreground.

We're using the [FocusIn/FocusOut](https://invisible-island.net/xterm/ctlseqs/ctlseqs.html#h3-FocusIn_FocusOut) sequences to communicate to ConPTY when a control gains/loses focus. Theoretically, other terminals could do this as well.

## References

#11682 tracks _real_ support for this sequence in Console & conpty. When we do that, we should consider even if a client application disables this mode, the Terminal & conpty should always request this from the hosting terminal (and just ignore internally to ConPTY).

See also #12515, #12526, which are the other two parts of this effort. This was tested with all three merged together, and they worked beautifully for all our scenarios. They are kept separate for ease of review.

## PR Checklist
* [x] This is prototype 3 for #2988
* [x] I work here
* [ ] Tests added/passed
* [n/a] Requires documentation to be updated

## Detailed Description of the Pull Request / Additional comments

This allows windows spawned by console processes to bring themselves to the foreground _when the console is focused_. (Historically, this is also called in the WndProc, when focus changes).

Notably, before this, ConPTY was _never_ focused, so windows could never bring themselves to the foreground when run from a ConPTY console. We're not blanket granting the SetForeground right to all console apps when run in ConPTY. It's the responsibility of the hosting terminal emulator to always tell ConPTY when a particular instance is focused.

95770ed9b2 Don't open a hole in the terminal window when pasting (#12208)
Turns out, this bug only repros in Controls version 2. I'm not sure why, but it didn't repro only on main. So this fix does nothing until #11720 merges.

This PR prevents us from setting properties on the paste warning dialog unless we actually need to paste. 5f9c551b7e proves that settings these properties is what would cause the bug in the first place. 

I went a step further and cleaned this up a bit. This was always a little weird, having to get the `BracketedPasteEnabled` for the active control on the UI thread before we actually display the warning. In the post-#5000 future where going back to the control like this would be a x-proc hop, I figured I should just skip that entirely and plumb the `BracketedPaste` state out in the initial request.

b3fab518f8 Prepare til wrappers for migrating off of SMALL_RECT (#11902)
This commit makes the following changes to `til::point/size/rectangle`
for the following reasons:
* Rename `rectangle` into `rect`
  This will make the naming consistent with a later `small_rect` struct
  as well as the existing Win32 POINT/SIZE/RECT structs.
* Standardizes til wrappers on `int32_t` instead of `ptrdiff_t`
  Provides a consistent behavior between x86 and x64, preventing accidental
  errors on x86, as it's less rigorously tested than x64. Additionally it
  improves interop with MIDL3 which only supports fixed width integer types.
* Standardizes til wrappers on throwing `gsl::narrow_error`
  Makes the behavior of our code more consistent.
* Makes all eligible functions `constexpr`
  Because why not.
* Removes implicit constructors and conversion operators
  This is a complex and controversial topic. My reasons are: You can't Ctrl+F
  for an implicit conversion. This breaks most non-IDE engines, like the one on
  GitHub or those we have internally at MS. This is important for me as these
  implicit conversion operators aren't cost free. Narrowing integers itself,
  as well as the boundary checks that need to be done have a certain,
  fixed overhead each time. Additionally the lack of noexcept prevents
  many advanced compiler optimizations. Removing their use entirely
  drops conhost's code segment size by around ~6.5%.

8dfdfc4d61 Simplify the handling of alpha values in the color table (#11900)
This PR attempts to minimize the amount of fiddling we do with the alpha
color components, by storing all colors with a zero alpha (the default
for `COLORREF` values) and then leaving it up to the renderer to adjust
the final alpha value as required (which it was already doing anyway).

This gets rid of the `argb.h` header file, which was originally being
used to produce `COLORREF` values with custom alpha components, and thus
is no longer required. Anywhere that was using the `ARGB` macro is now
using a standard `RGB` macro with a 0 alpha.

The `Utils::SetColorTableAlpha` method has also been removed, since that
was only really used to force an alpha of 255 on all the color table
entries, which isn't necessary.

There were also a number of places where we were using
`til::color::with_alpha`, to switch alpha components back and forth
between 0 and 255, which have now been removed. Some of these were
essentially noops, because the `til::color` class already applied the
appropriate alpha changes when converting from or to a `COLORREF`. 

I've manually run a few attribute rendering tests to check that the
colors were still working correctly, and the default background color is
appropriately transparent when in acrylic mode.

094273b995 Change the ControlCore layer to own a copy of its settings (#11619)
## Summary of the Pull Request

Currently, the TermControl and ControlCore recieve a settings object that implements `IControlSettings`. They use for this for both reading the settings they should use, and also storing some runtime overrides to those settings (namely, `Opacity`). The object they recieve currently is a `T.S.M.TerminalSettings` object, as well as another `TerminalSettings` object if the user wants to have an `unfocusedAppearance`. All these are all hosted in the same process, so everything is fine and dandy. 

With the upcoming move to having the Terminal split into multiple processes, this will no longer work. If the `ControlCore` in the Content Process is given a pointer to a `TerminalSettings` in a certain Window Process, and that control is subsequently moved to another window, then there's no guarantee that the original `TerminalSettings` object continues to exist. In this scenario, when window 1 is closed, now the Core is unable to read any settings, because the process that owned that object no longer exists. 

The solution to this issue is to have the `ControlCore`'s own their own copy of the settings they were created with. that way, they can be confident those settings will always exist. Enter `ControlSettings`, a dumb struct for just storing all the contents of the Settings. I used x-macros for this, so that we don't need to copy-paste into this file every time we add a setting. 

Changing this has all sorts of other fallout effects:
* Previewing a scheme/anything is a tad bit more annoying. Before, we could just sneak the previewed scheme into a `TerminalSettings` that lived between the settings we created the control with, and the settings they were actually using, and it would _just work_. Even explaining that here, it sounds like magic, because it was. However, now, the TermControl can't use a layered `TerminalSettings` for the settings anymore. Now we need to actually read out the current color table, and set the whole scheme when we change it. So now there's also a `Microsoft.Terminal.Core.Scheme` _struct_ for holding that data. 
  - Why a `struct`? Because that will go across the process boundary as a blob, rather than as a pointer to an object in the other process. That way we can transit the whole struct from window to core safely. 
* A TermControl doesn't have a `IControlSettings` at all anymore - it initalizes itself via the settings in the `Core`. This will be useful for tear-out, when we need to have the `TermControl` initialize itself from just a `ControlCore`, without being able to rebuild the settings from scratch.
* The `TabTests` that were written under the assumption that the Control had a layered `TerminalSettings` obviously broke, as they were designed to. They've been modified to reflect the new reality.
* When we initialize the Control, we give it the settings and the `UnfocusedAppearance` all at once. If we don't give it an `unfocusedAppearance`, it will just use the focused appearance as the unfocused appearance.
* The Control no longer can _write_ settings to the `ControlSettings`. We don't want to be storing things in there. Pretty much everything we set in the control, we store somewhere other than in the settings object itself. However, `opacity` and `useAcrylic`, we need to store in a handy new `RUNTIME_SETTING` property. We can write those runtime overrides to those properties.  
* We no longer store the color scheme for a pane in the persisted state. I'm tracking that in #9800. I don't think it's too hard to add back, but I wanted this in front of eyes sooner than later.

638c6d0291 Ensure automation peer is created regardless of terminal initialization (#10971)
## Summary of the Pull Request
The bug was that Narrator would still read the content of the old tab/pane although a new tab/pane was introduced. This is caused by the automation peer not being created when XAML requests it. Normally, we would prevent the automation peer from being created if the terminal was not fully initialized.

This change allows the automation peer to be created regardless of the terminal being fully initialized by...
- `TermControl`: `_InitializeTerminal` updates the padding (dependent on the `SwapChainPanel`) upon full initialization
- `ControlCore`: initialize the `_renderer` in the ctor so that we can attach the UIA Engine before `ControlCore::Initialize()` is called (dependent on `SwapChainPanel` loading)

As a bonus, this also fixes a locking issue where logging would attempt to get the text range's text and lock twice. The locking fix is very similar to #10937.

## Summary of the Pull Request

## Detailed Description of the Pull Request / Additional comments

This is kind of annoying that the auto-scrolling is handled by the TermControl, but it uses a timer that's still a WinUI construct.

We only want to start the auto-scrolling behavior when the drag started _inside_ the control. Otherwise, in the tab drag scenario, dragging into the bounds of the TermControl will trick it into thinking it should start a scroll.

7f3bc3cb04 Only access ControlInteractivity through the projection (#10051)
## Summary of the Pull Request

This forces the `TermControl` to only use `ControlCore` and `ControlInteractivity` via their WinRT projections. We want this, because WinRT projections can be used across process boundaries. In the future, `ControlCore` and `ControlInteractivity` are going to be living in a different process entirely from `TermControl`. By enforcing this boundary now, we can make sure that they will work seamlessly in the future.

## Detailed Description of the Pull Request / Additional comments

Most all this was just converting pure c++ types to winrt types when possible. I've added a couple helper projections with `til` converters, which made most of this really easy.

The "`MouseButtonState` needs to be composed of `Int32`s instead of `bool`s" is MENTAL. I have no idea why this is, but when I had the control OOP in the sample, that would crash when trying to de-marshal the bools. BODGY.

The biggest changes are in the way the UIA stuff is hooked up. The UiaEngine needs to be attached directly to the `Renderer`, and it can't be easily projected, so it needs to live next to the `ControlCore`. But the `TermControlAutomationPeer` needed the `UiaEngine` to help implement some interfaces.

Now, there's a new layer we've introduced. `InteractivityAutomationPeer` does the `ITextProvider`, `IControlAccessibilityInfo` and the `IUiaEventDispatcher` thing. `TermControlAutomationPeer` now has a 
`InteractivityAutomationPeer` stashed inside itself, so that it can ask the interactivity layer to do the real work. We still need the `TermControlAutomationPeer` though, to be able to attach to the real UI tree.

## Validation Steps Performed

The terminal behaves basically the same as before.

Most importantly, I whipped out Accessibility Insights, and the Terminal looks the same as before.

c3ca94ceca First three interactivity fixes (#9980)
## Summary of the Pull Request

This PR encompasses the first three bugs we found post-#9820.

### A: Mousedown, select, SCROLL does a weird thing with endpoints that doesn't happen in stable

We were using the terminal position to set the selection anchor, when we should have used the pixel position.

This is fixed in 4f4df01.

### B: Trackpad scrolling down with small increments seems buggy

This one's the most complicated.  The touchpad sends very many small scroll deltas, less than one row at a time. The control scrollbar can store a `double`, so small deltas can accumulate. Originally, these would accumulate in the scrollbar, and we'd only read that out as an `int` in the scrollbar updater, which is throttled. 

In the interactivity split, there's no place for us to store that double. We immediately narrow to an `int` for `ControlInteractivity::_updateScrollbar`. 

So this introduces a double inside `ControlInteractivity` as a fake scrollbar, with which to accumulate to. 

This is fixed in 33d29fa...0fefc5b

### C:  Looks like there's a selection issue when you click and drag too quickly.

The diff for this one is:

8910a16fd0 Split TermControl into a Core, Interactivity, and Control layer (#9820)
## Summary of the Pull Request

Brace yourselves, it's finally here. This PR does the dirty work of splitting the monolithic `TermControl` into three components. These components are: 

* `ControlCore`: This encapsulates the `Terminal` instance, the `DxEngine` and `Renderer`, and the `Connection`. This is intended to everything that someone might need to stand up a terminal instance in a control, but without any regard for how the UX works.
* `ControlInteractivity`: This is a wrapper for the `ControlCore`, which holds the logic for things like double-click, right click copy/paste, selection, etc. This is intended to be a UI framework-independent abstraction. The methods this layer exposes can be called the same from both the WinUI TermControl and the WPF control.
* `TermControl`: This is the UWP control. It's got a Core and Interactivity inside it, which it uses for the actual logic of the terminal itself. TermControl's main responsibility is now 

By splitting into smaller pieces, it will enable us to
* write unit tests for the `Core` and `Interactivity` bits, which we desparately need
* Combine `ControlCore` and `ControlInteractivity` in an out-of-proc core process in the future, to enable tab tearout.

However, we're not doing that work quite yet. There's still lots of work to be done to enable that, thought this is likely the biggest portion.

Ideally, this would just be methods moved wholesale from one file to another. Unfortunately, there are a bunch of cases where that didn't work as well as expected. Especially when trying to better enforce the boundary between the classes. 

We've got a couple tests here that I've added. These are partially examples, and partially things I ran into while implementing this. A bunch of things from #7001 can go in now that we have this.

This PR is gonna be a huge pain to review - 38 files with 3,730 additions and 1,661 deletions is nothing to scoff at. It will also conflict 100% with anything that's targeting `TermControl`. I'm hoping we can review this over the course of the next week and just be done with it, and leave plenty of runway for 1.9 bugs in post.

## Detailed Description of the Pull Request / Additional comments

* I don't love the names `ControlCore` and `ControlInteractivity`. Open to other names.
* I added a `ICoreState` interface for "properties that come from the `ControlCore`, but consumers of the `TermControl` need to know". In the future, these will all need to be handled specially, because they might involve an RPC call to retrieve the info from the core (or cache it) in the window process.
* I've added more `EventArgs` to make more events proper `TypedEvent`s.
* I've changed how the TerminalApp layer requests updated TaskbarProgress state. It doesn't need to pump TermControl to raise a new event anymore.
* ~~Something that snuck into this branch in the very long history is the switch to `DCompositionCreateSurfaceHandle` for the `DxEngine`. @miniksa wrote this originally in 30b8335, I'm just finally committing it here. We'll need that in the future for the out-of-proc stuff.~~
  * I reverted this in c113b65d9. We can revert _that_ commit when we want to come back to it.
* I've changed the acrylic handler a decent amount. But added tests!
* All the `ThrottledFunc` things are left in `TermControl`. Some might be able to move down into core/interactivity, but once we figure out how to use a different kind of Dispatcher (because a UI thread won't necessarily exist for those components).
* I've undoubtably messed up the merging of the locking around the appearance config stuff recently

## Validation Steps Performed

I've got a rolling list in https://github.com/microsoft/terminal/issues/6842#issuecomment-810990460 that I'm updating as I go.
