Update NavigateFocus function to use new visual-based navigation (#10756)
## Summary of the Pull Request
Uses the new logic to find visual neighbors of a pane to find which pane is the target when the move-focus commands are used. 

## References
It sounds like this logic will be refined later to meet #4692

## Detailed Description of the Pull Request / Additional comments

Its been a while since I've written C++ code, and it is my first time working on a Windows application. I hope that I have not made too many mistakes.

Work currently done:
- Add boilerplate/infrastructure for argument parsing, hotkeys, event handling
- Adds the `MovePane` function that finds the focused pane, and then tries to find
  a pane that is visually adjacent to according to direction.
- First pass at the `SwapPanes` function that swaps the tree location of two panes
- First working version of helpers `_FindFocusAndNeighbor` and `_FindNeighborFromFocus`
  that search the tree for the currently focused pane, and then climbs back up the tree
  to try to find a sibling pane that is adjacent to it. 
- An `_IsAdjacent' function that tests whether two panes, given their relative offsets, are adjacent to each other according to the direction.

Next steps:
- Once working these functions (`_FindFocusAndNeighbor`, etc) could be utilized to also solve #2398 by updating the `NavigateFocus` function.
- Do we want default hotkeys for the new actions?

<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
At this point, compilation and manual testing of functionality (with hotkeys) by creating panes, adding distinguishers to each pane, and then swapping them around to confirm they went to the right location.

Ignore closeOnExit when a conn. moves from Connecting to Failed (#10263)
ConptyConnection has two different failure modes:

1. We failed to initialize the pseudoconsole or create the process
2. The process exited with an error code.

Until this commit, they were treated the same way: closeOnExit=always
would force the pane/tab to be destroyed. This was very bad in case 1,
where we would display a (possibly useful) error message and then
immediately close the window.

This was made even worse by the change in #10045. We removed
startingDirectory validation and promoted it to an error message (so
that we could eventually let the connection handle startingDirectory in
its own way.) This of course revealed that a number of users had set
invalid starting directories… and those users included some who set
closeOnExit to always. Boom: instant "terminal opens and crashes"¹

In this commit, we introduce detection for a connection that fails
before it's been established. When that happens, we will ignore the
user's closeOnExit mode.

¹ It only looks like a crash; it's actually _technically_ functioning
properly.

Closes #10225.

Add a setting to flash the pane when BEL is emitted (#9270)
<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
Adds a new bellStyle called `window`. When `window` is set and a BEL is emitted, we flash the pane that emitted it. 

Additionally, changes bellStyle in the SUI to a list of checkboxes instead of radio buttons, to match bellStyle being a flag-enum. Deprecates 'BellStyle::Visual' in the schema, but still allows it to be set in the json (it maps to `Window | Taskbar`)

Add support for focusPane action, focus-pane subcommand (#10142)
## Summary of the Pull Request

Adds support for the `focusPane` action, and the `focus-pane` subcommand. These allow the user to focus a pane by it's ID. 

* `focusPane` accepts an `id`, identifying the id of the pane to focus.
* `focus-pane`, `fp` requires the parameter `--target,-t` to ID the pane it's going to focus.

## PR Checklist
* [x] Closes #5803
* [x] Closes #5464
* [x] I work here
* [x] Tests added/passed
* [ ] Requires documentation to be updated - oh no

## Detailed Description of the Pull Request / Additional comments

The ID isn't _totally_ useful right now, since users can't see them. But they're there, and used in-order. This is just slightly more ergonomic for complicated commandlines than `mf up; mf left`

## Validation Steps Performed

Tested in command palette
Tested a variety of commandlines. `wtd -w 0 mf down ; sp` and `wtd -w 0 fp -t 1 ; sp` gave me special difficulty.

Add support for a profile to specify an "unfocused" appearance (#8392)
This pull request adds an appearance configuration object to our
settings model and app lib, allowing the control to be rendered
differently depending on its state, and then uses it to add support for
an "unfocused" appearance that the terminal will use when it's not in
focus.

To accomplish this, we isolated the appearance-related settings from
Profile (into AppearanceConfig) and TerminalSettings (into the
IControlAppearance and ICoreAppearance interfaces). A bunch of work was
done to make inheritance work.

The unfocused appearance inherits from the focused one _for that
profile_. This is important: If you define a
defaults.unfocusedAppearance, it will apply all of defaults' settings to
any leaf profile when a terminal in that profile is out of focus.

Specified in #8345 
Closes #3062
Closes #2316

Separate between Close Tab Requested and Tab Closed flows (#9574)
## Summary of the Pull Request
Currently, both when the tab is already closed, and when there is a
request to close a tab (might be rejected), we go through the same flow
in TerminalPage.

This might leave the system in inconsistent state, as the side-effects
of closing will persist even if the closing was aborted.

This PR separates between the two flows, by introducing a CloseRequested
event to the TabBase.

This event is used to inform the upper tier (the terminal page) about
the request and to trigger the same logic that happens when the tab is
closed directly from the terminal page (e.g., by clicking close on the
tab view).

The Closed event will be  used only to handle the actual closing of the
tab. It will ensure that the tab gets removed from the terminal page if
required.

As a result, it a read-only pane will be closed non-interactively (aka
connection exits), the tab closed flow will be invoked, and no user
prompt will be shown.

Move events out of TermControl.h ; Use TYPED_EVENT in more places (#9526)
This is a small refactor on my way to much bigger, more painful refactors. This PR does five things:

* `TermControl.*` has historically had all the control-relevant EventArgs defined in the same file as TermControl. That's just added clutter to the files, clutter that could have been in it's own place.  We'll move all those event arg to their own files. 
* We'll also move `IDirectKeyListener` to its own file while we're at it.
* We'll update some of `TermControl`'s old `DEFINE`/`DECLARE_TYPED_EVENT` macros to the newer `TYPED_EVENT` macro, which is a bit nicer. 
* We'll change `TermControl.TitleChanged` to a typed event. I needed that for a future PR, so let's just do it here
* While we're updating `TYPED_EVENT` macros, let's do `TerminalPage` too.

Rename Microsoft.Terminal.TerminalControl to .Control; Split into dll & lib (#9472)
**BE NOT AFRAID**. I know that there's 107 files in this PR, but almost
all of it is just find/replacing `TerminalControl` with `Control`.

This is the start of the work to move TermControl into multiple pieces,
for #5000. The PR starts this work by:
* Splits `TerminalControl` into separate lib and dll projects. We'll
  want control tests in the future, and for that, we'll need a lib.
* Moves `ICoreSettings` back into the `Microsoft.Terminal.Core`
  namespace. We'll have other types in there soon too. 
  * I could not tell you why this works suddenly. New VS versions? New
    cppwinrt version? Maybe we're just better at dealing with mdmerge
    bugs these days.
* RENAMES  `Microsoft.Terminal.TerminalControl` to
  `Microsoft.Terminal.Control`. This touches pretty much every file in
  the sln. Sorry about that (not sorry). 

An upcoming PR will move much of the logic in TermControl into a new
`ControlCore` class that we'll add in `Microsoft.Terminal.Core`.
`ControlCore` will then be unittest-able in the
`UnitTests_TerminalCore`, which will help prevent regressions like #9455 

## Detailed Description of the Pull Request / Additional comments
You're really gonna want to clean the sln first, then merge this into
your branch, then rebuild. It's very likely that old winmds will get
left behind. If you see something like 

```
Error    MDM2007    Cannot create type
Microsoft.Terminal.TerminalControl.KeyModifiers in read-only metadata
file Microsoft.Terminal.TerminalControl.
```

then that's what happened to you.

Move TerminalSettings from TermApp to TerminalSettingsModel (#9318)
This accomplishes the first step towards embedding a preview on the Profiles/ColorSchemes page, by moving the `TerminalSettings` object over to the Terminal Settings Model project. We'll leverage this in a later PR to construct an embedded terminal in the settings UI.

`TerminalSettings` had to see a few more functions exposed in the IDL
(including some inheritance stuff).

Refresh the JSON to make TerminalSettings do it's thing across all the
open terminals.

Separate runtime TerminalSettings from profile-TerminalSettings (#8602)
<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
The TerminalSettings object we create from profiles no longer gets passed into the control, instead, a child of that object gets passed into the control. Any overrides the control makes to the settings then live in the child. So, when we do a settings reload, we simply update the child's parent and the overrides will remain.

Fix crash when closing multiple splits from the tab context menu (#9028)
## 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.

## 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.

Fix exiting a zoomed pane (#7973)
## Summary of the Pull Request

Fixes the bug where `exit`ing inside a closed pane would leave the Terminal blank.

Additionally, removes `Tab::GetRootElement` and replaces it with the _observable_ `Tab::Content`. This should be more resilient in the future.

Also adds some tests, though admittedly not for this exact scenario. This scenario requires a cooperating TerminalConnection that I can drive for the sake of testing, and _ain't nobody got time for that_.

## Detailed Description of the Pull Request / Additional comments

From notes I had left in `Tab.cpp` while I was working on this:
```
OKAY I see what's happening here the ActivePaneChanged Handler in TerminalPage
doesn't re-attach the tab content to the tree, it just updates the title of the
window.

So when the pane is `exit`ed, the pane's control is removed and re-attached to
the parent grid, which _isn't in the XAML tree_. And no one can go tell the
TerminalPage that it needs to re set up the tab content again.

The Page _manually_ does this in a few places, when various pane actions are
about to take place, it'll unzoom. It would be way easier if the Tab could just
manage the content of the page.

Or if the Tab just had a Content that was observable, that when that changed,
the page would auto readjust. That does sound like a LOT of work though.

Add a setting to configure the audible bell (#7793)
Adds a new setting, `bellStyle`, to be able to disable the audible bell
added in #7679. Currently, this setting accepts two values:
* `audible`: play a noise on a bell
* `none`: Don't play a noise.

In the future, we can add a `"bellStyle": "visible"` for flashing the
Terminal instead of making a noise on bell.

## Validation Steps Performed
Pressing <kbd>Ctrl+G</kbd> in cmd, and hitting enter is an easy way of
triggering a bell. I set the setting to `none`, and presto, the bell
stopped.

Add an animation to pane entrance/exit (#7364)
Adds an entrance animation when panes are created. This animation can be
disabled with the `disableAnimations` global setting. 

Although the XAML animation documentation was pretty heavy on the _do it
in XAML_ route, our panes are created pretty much entirely in code, so
we've got to create the animations in code as well. 

200ms as the duration of the animation was picked _super_ arbitrarily.
300ms felt too long, and 166ms felt like it was only visible for a
single frame.

as WinRT objects.

In the process of ripping out TSM from TerminalApp, a few other changes
were made to make this possible:
1. AppLogic's `ApplicationDisplayName` and `ApplicationVersion` was
   moved to `CascadiaSettings`
   - These are defined as static functions. They also no longer check if
     `AppLogic::Current()` is nullptr.
2. `enum LaunchMode` was moved from TerminalApp to TSM
3. `AzureConnectionType` and `TelnetConnectionType` were moved from the
   profile generators to their respective TerminalConnections
4. CascadiaSettings' `SettingsPath` and `DefaultSettingsPath` are
   exposed as `hstring` instead of `std::filesystem::path`
5. `Command::ExpandCommands()` was exposed via the IDL
   - This required some of the warnings to be saved to an `IVector`
     instead of `std::vector`, among some other small changes.
6. The localization resources had to be split into two halves.
   - Resource file linked in init.cpp. Verified at runtime thanks to the
     StaticResourceLoader.
7. Added constructors to some `ActionArgs`
8. Utils.h/cpp were moved to `cascadia/inc`. `JsonKey()` was moved to
   `JsonUtils`. Both TermApp and TSM need access to Utils.h/cpp.

A large amount of work includes moving to the new namespace
(`TerminalApp` --> `Microsoft::Terminal::Settings::Model`).

Fixing the tests had its own complications. Testing required us to split
up TSM into a DLL and LIB, similar to TermApp. Discussion on creating a
non-local test variant can be found in #7743.

Make CascadiaSettings a WinRT object (#7457)
CascadiaSettings is now a WinRT object in the TerminalApp project.

## References
#7141 - CascadiaSettings is a settings object
#885 - this new settings object will be moved to a new TerminalSettingsModel project

This one _looks_ big, but most of it is really just propagating the
changes to the tests. In fact, you can probably save yourself some time
because the tests were about an hour of Find&Replace.

`CascadiaSettings::GetCurrentAppSettings()` was only being used in
Pane.cpp. So I ripped out the 3 lines of code and stuffed them in there.

Follow-up work:
- There's a few places in AppLogic where I `get_self` to be able to get
  the warnings out. This will go away in the next PR (wrapping up #885)

Make Profile a WinRT object (#7283)
Profile is now a WinRT object in the TerminalApp project.

As with ColorScheme, all of the serialization logic is not exposed via
the idl. TerminalSetingsModel will handle it when it's all moved over.

I removed the "Get" and "Set" prefixes from all of the Profile
functions. It just makes more sense to use the `GETSET_PROPERTY` macro
to do most of the work for us.

`CloseOnExitMode` is now an enum off of the Profile.idl.

`std::optional<wstring>` got converted to `hstring` (as opposed to
`IReference<hstring>`). `IReference<hstring>` is not valid to MIDL.

Add a togglePaneZoom action for zooming a pane (#6989)
This PR adds the `togglePaneZoom` action, which can be used to make a
pane expand to fill the entire contents of the window.  A tab that
contains a zoomed pane will have a magnifying glass icon prepended
to its title. Any attempts to manage panes with one zoomed will force
the zoomed pane back to normal size.

VALIDATION

Move ICore/ControlSettings to TerminalControl project (#7167)
## Summary of the Pull Request
Move `ICoreSettings` and `IControlSettings` from the TerminalSettings project to the TerminalCore and TerminalControl projects respectively. Also entirely removes the TerminalSettings project.

The purpose of these interfaces is unchanged. `ICoreSettings` is used to instantiate a terminal. `IControlSettings` (which requires an `ICoreSettings`) is used to instantiate a UWP terminal control.

## Detailed Description of the Pull Request / Additional comments

One important part of this change concerns how panes are initialized at runtime. We've had some persistent trouble with initializing multiple panes, because they rely on knowing how big they'll actually be, to be able to determine if they can split again. 

We previously worked around this by ignoring the size check when we were in "startup", processing an initial commandline. This PR however requires us to be able to know the initial size of a pane at runtime, but before the parents have necessarily been added to the tree, or had their renderer's set up.

This led to the development of `Pane::PreCalculateCanSplit`, which is very highly similar to `Pane::PreCalculateAutoSplit`. This method attempts to figure out how big a pane _will_ take, before the parent has necessarily laid out. 

This also involves a small change to `TermControl`, because if its renderer hasn't been set up yet, it'll always think the font is `{0, fontHeight}`, which will let the Terminal keep splitting in the x direction. This change also makes the TermControl set up a renderer to get the real font size when it hasn't yet been initialized.

This was what the json blob I was using for testing evolved into

```json
        {
            "command": {
                "action":"wt",
                "commandline": "new-tab cmd.exe /k #work 15 ; split-pane cmd.exe /k #work 15 ; split-pane cmd.exe /k media-commandline ; new-tab powershell dev\\symbols.ps1 ; new-tab -p \"Ubuntu\" ; new-tab -p \"haunter.gif\" ; focus-tab -t 0",

            },
            "keys": ["ctrl+shift+n"]
        }
```

I also added some tests.

Process actions sync. on startup; don't dupe nonexistent profile (#5090)
This PR has evolved to encapsulate two related fixes that I can't really
untie anymore.

#2455 - Duplicating a tab that doesn't exist anymore

This was the bug I was originally fixing in #4429. 

When the user tries to `duplicateTab` with a profile that doesn't exist
anymore (like might happen after a settings reload), don't crash.

As I was going about adding tests for this, got blocked by the fact that
the Terminal couldn't open _any_ panes while the `TerminalPage` was size
0x0. This had two theoretical solutions: 

* Fake the `TerminalPage` into thinking it had a real size in the test -
  probably possible, though I'm unsure how it would work in practice.
* Change `Pane`s to not require an `ActualWidth`, `ActualHeight` on
  initialization. 

Fortuately, the second option was something else that was already on my
backlog of bugs. 

#4618 - `wt` command-line can't consistently parse more than one arg

Presently, the Terminal just arbitrarily dispatches a bunch of handlers
to try and handle all the commands provided on the commandline. That's
lead to a bunch of reports that not all the commands will always get
executed, nor will they all get executed in the same order. 

This PR also changes the `TerminalPage` to be able to dispatch all the
commands sequentially, all at once in the startup. No longer will there
be a hot second where the commands seem to execute themselves in from of
the user - they'll all happen behind the scenes on startup. 

This involved a couple other changes areound the `TerminalPage`
* I had to make sure that panes could be opened at a 0x0 size. Now they
  use a star sizing based off the percentage of the parent they're
  supposed to consume, so that when the parent _does_ get laid out,
  they'll take the appropriate size of that parent.
* I had to do some math ahead of time to try and calculate what a
  `SplitState::Automatic` would be evaluated as, despite the fact that
  we don't actually know how big the pane will be. 
* I had to ensure that `focus-tab` commands appropriately mark a single
  tab as focused while we're in startup, without roundtripping to the
  Dispatcher thread and back

## Detailed Description of the Pull Request / Additional comments

`CascadiaSettings::BuildSettings` can throw if the GUID doesn't exist.
This wraps those calls up with a try/catch.

It also adds a couple tests - a few `SettingsTests` for try/catching
this state. It also adds a XAML-y test in `TabTests` that creates a
`TerminalPage` and then performs som UI-like actions on it. This test
required a minor change to how we generate the new tab dropdown - in the
tests, `Application::Current()` is _not_ a `TerminalApp::App`, so it
doesn't have a `Logic()` to query. So wrap that in a try/catch as well.

While working on these tests, I found that we'd crash pretty agressively
for mysterious reasons if the TestHostApp became focused while the test
was running. This was due to a call in
`TSFInputControl::NotifyFocusEnter` that would callback to
`TSFInputControl::_layoutRequested`, which would crash on setting the
`MaxSize` of the canvas to a negative value. This PR includes a hotfix
for that bug as well.

Star sizing allows us to keep things proportional. Since a 1::1 proportion is the same as a 100::100 proportion, I just went in and added star sizing. In the words of a some dude with a big metal fist, everything is perfectly balanced now.

<!-- Provide a more detailed description of the PR, other things fixed or any additional comments/features here -->
## Detailed Description of the Pull Request / Additional comments
My thought pattern here was to minimally disturb the existing code where possible. So where I could, I converted existing functions into coroutine using functions (like in the [core example](https://github.com/microsoft/terminal/issues/3919#issue-536598706)). For ~the most part~ all instances, I used the format where [`this` is accessed safely within a locked scope](https://github.com/microsoft/terminal/issues/3919#issuecomment-564730620). Some function signatures were changed to take objects by value instead of reference, so the coroutines don't crash when the objects are accessed past their original lifetime. The [copy](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalApp/TerminalPage.cpp#L1132) and [paste](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalApp/TerminalPage.cpp#L1170) event handler entry points were originally set to a high priority; however, the WinRT coroutines don't appear to support a priority scheme so this priority setting was not preserved in the translation.

Compiles and runs, and for every event with a clear trigger repro, I triggered it to ensure crashes weren't introduced.

mcpiroman d4c527607a Snap to character grid when resizing window (#3181)
When user resizes window, snap the size to align with the character grid
(like e.g. putty, mintty and most unix terminals). Properly resolves
arbitrary pane configuration (even with different font sizes and
padding) trying to align each pane as close as possible.

It also fixes terminal minimum size enforcement which was not quite well
handled, especially with multiple panes.

This PR does not however try to keep the terminals aligned at other user
actions (e.g. font change or pane split). That is to be tracked by some
other activity.

Snapping is resolved in the pane tree, recursively, so it (hopefully)
works for any possible layout.

Along the way I had to clean up some things as so to make the resulting
code not so cumbersome:
1. Pane.cpp: Replaced _firstPercent and _secondPercent with single
   _desiredSplitPosition to reduce invariants - these had to be kept in
   sync so their sum always gives 1 (and were not really a percent). The
   desired part refers to fact that since panes are aligned, there is
   usually some deviation from that ratio.
2. Pane.cpp: Fixed _GetMinSize() - it was improperly accounting for
   split direction
3. TerminalControl: Made dedicated member for padding instead of
   reading it from a control itself. This is because the winrt property
   functions turned out to be slow and this algorithm needs to access it
   many times. I also cached scrollbar width for the same reason.
4. AppHost: Moved window to client size resolution to virtual method,
   where IslandWindow and NonClientIslandWindow have their own
   implementations (as opposite to pointer casting).

One problem with current implementation is I had to make a long call
chain from the window that requests snapping to the (root) pane that
implements it: IslandWindow -> AppHost's callback -> App ->
TerminalPage -> Tab -> Pane. I don't know if this can be done better.

## Validation Steps Performed
Spam split pane buttons, randomly change font sizes with ctrl+mouse
wheel and drag the window back and forth.

Mike Griese 2e26c3e0c9 Add support for "Automatic" splits (#4025)
## Summary of the Pull Request

Adds support for `auto` as a potential value for a `splitPane` keybinding's `split` argument. For example:

```json
        { "keys": [ "ctrl+shift+z" ], "command": { "action": "splitPane", "profile": "matrix", "commandline": "cmd.exe", "split":"auto" } },
```

When set to `auto`, Panes will decide which direction to split based on the available space within the terminal. If the pane is wider than it is tall, the pane will introduce a new vertical split (and vice-versa).

Mike Griese 9145903e11 Fix the TabTests! (#3833)
## Summary of the Pull Request

Fix the `TabTests`, and enable testing of types with XAML content. The `TabTests` were written many, many moons ago. they were intended to be our tests of XAML-like content within the Terminal app, so we could have unittests of Tabs, Panes, etc. Between their initial authoring and the day they were checked in, we had a bunch of build changes come in and break them irreperably. 

We've gotten them fixed now with _one weird trick_ <sup>doctors hate me</sup>. As long as there isn't an `App.xbf` in the test's output directory, then the tests will deploy just fine.

We also needed a bit of magic, cribbed straight from TAEF, to enable running test code synchronously on the UI thread. Hence, `CppwinrtTailored.h`.

Implement ConnectionState and closeOnExit=graceful/always/never (#3623)
This pull request implements the new
`ITerminalConnection::ConnectionState` interface (enum, event) and
connects it through TerminalControl to Pane, Tab and App as specified in
#2039. It does so to implement `closeOnExit` = `graceful` in addition to
the other two normal CoE types.

It also:

* exposes the singleton `CascadiaSettings` through a function that
  looks it up by using the current Xaml application's `AppLogic`.
  * In so doing, we've broken up the weird runaround where App tells
    TerminalSettings to CloseOnExit and then later another part of App
    _asks TerminalControl_ to tell it what TerminalSettings said App
    told it earlier. `:crazy_eyes:`
* wires up a bunch of connection state points to `AzureConnection`.
  This required moving the Azure connection's state machine to use another
  enum name (oops).
* ships a helper class for managing connection state transitions.
* contains a bunch of template magic.
* introduces `WINRT_CALLBACK`, a oneshot callback like `TYPED_EVENT`.
* replaces a bunch of disparate `_connecting` and `_closing` members
  with just one uberstate.
* updates the JSON schema and defaults to prefer closeOnExit: graceful
* updates all relevant documentation

Decouple "Active Terminal" and "Focused Control" (#3540)
## Summary of the Pull Request

Unties the concept of "focused control" from "active control".

Previously, we were exclusively using the "Focused" state of `TermControl`s to determine which one was active. This was fraught with gotchas - if anything else became focused, then suddenly there was _no_ pane focused in the Tab. This happened especially frequently if the user clicked on a tab to focus the window. Furthermore, in experimental branches with more UI added to the Terminal (such as [dev/migrie/f/2046-command-palette](https://github.com/microsoft/terminal/tree/dev/migrie/f/2046-command-palette)), when these UIs were added to the Terminal, they'd take focus, which again meant that there was no focused pane.

This fixes these issue by having each Tab manually track which Pane is active in that tab. The Tab is now the arbiter of who in the tree is "active". Panes still track this state, for them to be able to MoveFocus appropriately. 

It also contains a related fix to prevent the tab separator from stealing focus from the TermControl. This required us to set the color of the un-focused Pane border to some color other that Transparent, so I went with the TabViewBackground. Panes now look like the following:

## Detailed Description of the Pull Request / Additional comments

I've removed the simple Grid we were using as the pane separator, and replaced it with a Border that might appear on any side of a pane.

When we add a split, we'll create each child with one of the `Border` flags set (each child with one of a pair of flags). E.g. creating a horizontal split creates one child with the `Top` border, and another with the `Bottom`. 

Then, if one of those panes is split, it will pass it's border flag to is new children, with the additional flag set. So adding another Vertical split to the above scenario would create a set of panes with either (`Top|Left`, `Top|Right`) or (`Bottom|Left`, `Bottom|Right`) borders set, depending on which pane was split.

* start work on this by tracking border state

* Colorize the border

* Use the accent color for highlighting

* Cleanup the accent color code

* Don't buy any rural real estate when closing a pane

* Closing panes works well now too

* Cleanup for review

* Update src/cascadia/TerminalApp/Pane.cpp

* try some things that don't work to fix the resizing crash

* Revert "try some things that don't work to fix the resizing crash"

This reverts commit 3fc14da113.

* this _does_ work, but I think it's not semantically correct

* This doesn't seem to work either.

  I tried adding the pane seperators to the Pane::_GetMinWidth calculation. That
  works for prevent the crash, but the resizing is wonky now. If you add a
  Vertical split, then a second, then resize the middle pane really small,
  you'll see that the _last_ resize doesn't work properly. The text seems to
  overhand into the border.

  Additionally, there's really weird behavior resizing panes to be small. They
  don't always seem to be resizable to the smallest size.

* Revert "This doesn't seem to work either."

This reverts commit 2fd8323e7b.

* Merge the changes from the "this is the one" branch

  Again, no idea what I really did that worked, but it does

* Cleanup from my mess of a commit

  This makes so much more sense now

* Other PR feedback from @carlos-zamora

* Fix a typo

Richard Szalay f4294b17d7 Clean up Pane (#2494)
* Merge pane splitting methods

Having separate Horizontal/Vertical versions made it hard to manage, and App.cpp already made use of Pane::SplitState so it made sense to have that be the descriminator

* Rename Tab::(Can)AddSplit to (Can)SplitPane to align with Pane methods

Split was used as a noun in Tab but a verb in Pane, which felt odd

* Remove unused local variable in Pane::_CanSplit

* Remove redundant 'else' branches in Pane

Improves readibility for all 'low hanging fruit' cases where the 'if' was returning.

Richard Szalay 09d79cb422 Prevent splitting panes into 0 width/height #2401 (#2450)
Fixes a crash that can occur when splitting pane that was so small that the target panes would have a width/height of 0, causing DxRenderer to fail when creating the device resources.

This PR prevents both the call to `App::AddHorizontal/VerticalSplit` and the creation of the `TermControl` if the split would fail.

Closes #2401

## Details

`App::_SplitPane` calls `focusedTab->CanAddHorizontalSplit/CanAddHorizontalSplit` before it initializes the `TermControl` to avoid having to deal with the cleanup. If a split cannot occur, it will simply return. 

**Question: Should we beep or something here?**

It then follows the same naming/flow style as the split operation, so: `Tab::CanAddHorizontalSplit -> Pane::CanSplitHorizontal ->Pane::_CanSplit`. The public pane methods will handle leaf/child the same as the current Split methods.

`_CanSplit` reuses existing logic like `_root.GetActualWidth/Height`, `Pane::_GetMinSize`, and the `Half` constant.

## Validation Steps Performed

1. Open a new tab
2. Attempt to split horizontally/vertically more than 6-8 times

Success: Pane will will eventually stop splitting rather than crashing the process.

Carlos Zamora a08666b58e Accessibility: TermControl Automation Peer (#2083)
Builds on the work of #1691 and #1915 

Let's start with the easy change:
- `TermControl`'s `controlRoot` was removed. `TermControl` is a `UserControl`
  now.

Ok. Now we've got a story to tell here....

### TermControlAP - the Automation Peer
Here's an in-depth guide on custom automation peers:
https://docs.microsoft.com/en-us/windows/uwp/design/accessibility/custom-automation-peers

We have a custom XAML element (TermControl). So XAML can't really hold our
hands and determine an accessible behavior for us. So this automation peer is
responsible for enabling that interaction.

We made it a FrameworkElementAutomationPeer to get as much accessibility as
possible from it just being a XAML element (i.e.: where are we on the screen?
what are my dimensions?). This is recommended. Any functions with "Core" at the
end, are overwritten here to tweak this automation peer into what we really
need.

But what kind of interactions can a user expect from this XAML element?
Introducing ControlPatterns! There's a ton of interfaces that just define "what
can I do". Thankfully, we already know that we're supposed to be
`ScreenInfoUiaProvider` and that was an `ITextProvider`, so let's just make the
TermControlAP an `ITextProvider` too.

So now we have a way to define what accessible actions can be performed on us,
but what should those actions do? Well let's just use the automation providers
from ConHost that are now in a shared space! (Note: this is a great place to
stop and get some coffee. We're about to hop into the .cpp file in the next
section)


### Wrapping our shared Automation Providers

Unfortunately, we can't just use the automation providers from ConHost. Or, at
least not just hook them up as easily as we wish. ConHost's UIA Providers were
written using UIAutomationCore and ITextRangeProiuder. XAML's interfaces
ITextProvider and ITextRangeProvider are lined up to be exactly the same.

So we need to wrap our ConHost UIA Providers (UIAutomationCore) with the XAML
ones. We had two providers, so that means we have two wrappers.

#### TermControlAP (XAML) <----> ScreenInfoUiaProvider (UIAutomationCore)
Each of the functions in the pragma region `ITextProvider` for
TermControlAP.cpp is just wrapping what we do in `ScreenInfoUiaProvider`, and
returning an acceptable version of it.

Most of `ScreenInfoUiaProvider`'s functions return `UiaTextRange`s. So we need
to wrap that too. That's this next section...

#### XamlUiaTextRange (XAML) <----> UiaTextRange (UIAutomationCore)
Same idea.  We're wrapping everything that we could do with `UiaTextRange` and
putting it inside of `XamlUiaTextRange`.


### Additional changes to `UiaTextRange` and `ScreenInfoUiaProvider`
If you don't know what I just said, please read this background:
- #1691: how accessibility works and the general responsibility of these two
  classes
- #1915: how we pulled these Accessibility Providers into a shared area

TL;DR: `ScreenInfoUiaProvider` lets you interact with the displayed text.
`UiaTextRange` is specific ranges of text in the display and navigate the text.

Thankfully, we didn't do many changes here. I feel like some of it is hacked
together but now that we have a somewhat working system, making changes
shouldn't be too hard...I hope.

#### UiaTextRange
We don't have access to the window handle. We really only need it to draw the
bounding rects using WinUser's `ScreenToClient()` and `ClientToScreen()`. I
need to figure out how to get around this.

In the meantime, I made the window handle optional. And if we don't have
one....well, we need to figure that out. But other than that, we have a
`UiaTextRange`.

#### ScreenInfoUiaProvider
At some point, we need to hook up this automation provider to the
WindowUiaProvider. This should help with navigation of the UIA Tree and make
everything just look waaaay better. For now, let's just do the same approach
and make the pUiaParent optional.

This one's the one I'm not that proud of, but it works. We need the parent to
get a bounding rect of the terminal. While we figure out how to attach the
WindowUiaProvider, we should at the very least be able to get a bunch of info
from our xaml automation peer. So, I've added a _getBoundingRect optional
function. This is what's called when we don't have a WindowUiaProvider as our
parent.


## Validation Steps Performed
I've been using inspect.exe to see the UIA tree.
I was able to interact with the terminal mostly fine. A few known issues below.

Unfortunately, I tried running Narrator on this and it didn't seem to like it
(by that I mean WT crashed). Then again, I don't really know how to use
narrator other than "click on object" --> "listen voice". I feel like there's a
way to get the other interactions with narrator, but I'll be looking into more
of that soon. I bet if I fix the two issues below, Narrator will be happy.

## Miscellaneous Known Issues
- `GetSelection()` and `GetVisibleRanges()` crashes. I need to debug through
  these. I want to include them in this PR.

Fixes #1353.

Mike Griese 5074335392 Add a keybinding for ClosePane (#2012)
Closes #993
  When the last pane in a tab is closed, the tab will close.
  Bound to Ctrl+Shift+W by default. See #1417 for discussion on the default
  keybindings. The Ctrl+W->CloseTab keybinding is being removed in favor of
  ClosePane.

Add support for moving focus between panes with the keyboard (#1910)
Enables the user to set keybindings to move focus between panes with the keyboard. 
This is highly based off the work done for resizing panes. Same logic applies - 
  moving focus will move up the panes tree until we find a pane to move the focus to.

Mike Griese 2de2f445c7
Enable resizing the panes with the keyboard. (#1207)
Adds the ability to resize panes with the keyboard. 

This is accomplished by making the Column/RowDefinitions for a Pane use `GridLengthHelper::FromPixels` to set their size. We store a pair of floats that represents the relative amount that each pane takes out of the parent pane. When the window is resized, we use that percentage to figure out the new size of each child in pixels, and manually size each column. 

Then, when the user presses the keybindings for resizePane{Left/Right/Up/Down}, we'll adjust those percentages, and resize the rows/cols as appropriate.

Currently, each pane adjusts the width/height by 5% of the total size at a time. I am not in love with this, but it works for now. I think when we get support for keybindings with arbitrary arg blobs, then we could do either a percent movement, or a number of characters at a time. The number of characters one would be trickier, because we'd have to get the focused control, and get the number of pixels per character, as adjacent panes might not have the same font sizes.
