## Detailed Description of the Pull Request / Additional comments
### Background
- We want the Terminal to be fast at drawing. To be fast at drawing, we perform differential drawing, or only drawing what is different from the previous frame. We use DXGI's `Present1` method to help us with this as it helps us compose only the deltas onto the previous frame at drawing time and assists us in scrolling regions from the previous frame without intervention. However, it only works on strictly integer pixel row heights.
- Most of the hit testing and size-calculation logic in both the `conhost` and the Terminal products are based on the size of an individual cell. Historically, a cell was always dictated in a `COORD` structure, or two `SHORT` values... which are integers. As such, when we specify the space for any individual glyph to be displayed inside our terminal drawing region, we want it to fall perfectly inside of an integer box to ensure all these other algorithms work correctly and continue to do so.
- Finally, we want the Terminal to have font fallback and locate glyphs that aren't in the primary selected font from any other font it can find on the system that contains the glyph, per DirectWrite's font fallback mechanisms. These glyphs won't necessarily have the same font or glyph metrics as the base font, but we need them to fit inside the same cell dimensions as if they did because the hit testing and other algorithms aren't aware of which particular font is sourcing each glyph, just the dimensions of the bounding box per cell.
### How does Terminal deal with this?
- When we select a font, we perform some calculations using the design metrics of the font and glyphs to determine how we could fit them inside a cell with integer dimensions. Our process here is that we take the requested font size (which is generally a proxy for height), find the matching glyph width for that height then round it to an integer. We back convert from that now integer width to a height value which is almost certainly now a floating point number. But because we need an integer box value, we add line padding above and below the glyphs to ensure that the height is an integer as well as the width. Finally, we don't add the padding strictly equally. We attempt to align the English baseline of the glyph box directly onto an integer pixel multiple so most characters sit crisply on a line when displayed.
- Note that fonts and their glyphs have a prescribed baseline, line gap, and advance values. We use those as guidelines to get us started, but then to meet our requirements, we pad out from those. This results in fonts that should be properly authored showing gaps. It also results in fonts that are improperly authored looking even worse than they normally would.
### Now how does block and line drawing come in?
- Block and Line drawing glyphs are generally authored so they will look fine when the font and glyph metrics are followed exactly as prescribed by the font. (For some fonts, this still isn't true and we want them to look fine anyway.)
- When we add additional padding or rounding to make glyphs fit inside of a cell, we can be adding more space than was prescribed around these glyphs. This can cause a gap to be visible.
- Additionally, when we move things like baselines to land on a perfect integer pixel, we may be drawing a glyph lower in the bounding box than was prescribed originally.
### And how do we solve it?
- We identify all glyphs in the line and block drawing ranges.
- We find the bounding boxes of both the cell and the glyph.
- We compare the height of the glyph to the height of the cell to see if we need to scale. We prescribe a scale transform if the glyph wouldn't be tall enough to fit the box. (We leave it alone otherwise as some glyphs intentionally overscan the box and scaling them can cause banding effects.)
- We inspect the overhang/underhang above and below the boxes and translate transform them (slide them) so they cover the entire cell area.
- We repeat the previous two steps but in the horizontal direction.

## Summary of the Pull Request
Simple fix to update the example documentation with the recent changes to 0.11.
Literally just <kbd>ctrl+f</kbd> find-and-replace all the old `profiles.json` that are sitting around in the repo with `settings.json`. I didn't touch the specs, since it seemed better to leave them in the state that they were originally authored in.

* [x] I work here.

These were already in the `SettingsSchema.md`, so I just updated the `profiles.schema.json` to have the descriptions as well.

* [x] This is docs.
It was brought to our attention that shipping a font with ligatures as our default
font could be an accessibility issue for the visually-impaired. Unfortunately, we
don't have a renderer setting to disable ligatures (#759). Fortunately however, we
DO already have a version of Cascadia that doesn't have ligatures.
If we ship that and set it as our default font, we'll at least let people _opt_ to
have ligatures enabled by switching from `Cascadia Mono` to `Cascadia Code`.

## Summary of the Pull Request
Implements `copyFormatting` as a global setting. When enabled, formatting such as font and foreground/background colors are copied to the clipboard on _all_ copy operations.
Also updates the schema and docs.

We already check if the hstring passed into the clipboard is empty before setting it. So the majority of the changes are actually just adding the global setting in.

## Summary of the Pull Request
Minor cleanup on the schema. Globals isn't accepted anymore,
so the schema should not help you autocomplete anymore.
## Validation Steps Performed
Imported the new schema. You do _not_ get a warning when globals
is in. But, the schema won't suggest things when inside globals.
It's just treated as an unknown item.
However, "defaultProfile" is still required (more of a sanity test)
## Summary of the Pull Request
Added `splitMode` to settings schema JSON and md files.
The definition might need some tweaking.

This pull request migrates `profiles.json` to `settings.json` and removes the legacy roaming AppData settings migrator.
It also:
* separates the key bindings in defaults.json into logical groups
* syncs the universal terminal defaults with the primary defaults
* removes some stray newlines that ended up at the beginning of settings.json and defaults.json
Fixes#5186.
Fixes#3291.
### categorize key bindings
### sync universal with main
### kill stray newlines in template files
### move profiles.json to settings.json
This commit also changes Get*Settings from returning a string to
returning a std::filesystem::path. We gain in expressiveness without a
loss in clarity (since path still supports .c_str()).
NOTE: I tried to do an atomic rename with the handle open, but it didn't
work for reparse points (it moves the destination of a symbolic link
out into the settings folder directly.)
(snip for atomic rename code)
```c++
auto path{ pathToSettingsFile.wstring() };
auto renameBufferSize{ sizeof(FILE_RENAME_INFO) + (path.size() * sizeof(wchar_t)) };
auto renameBuffer{ std::make_unique<std::byte[]>(renameBufferSize) };
auto renameInfo{ reinterpret_cast<FILE_RENAME_INFO*>(renameBuffer.get()) };
renameInfo->Flags = FILE_RENAME_FLAG_REPLACE_IF_EXISTS | FILE_RENAME_FLAG_POSIX_SEMANTICS;
renameInfo->RootDirectory = nullptr;
renameInfo->FileNameLength = gsl::narrow_cast<DWORD>(path.size());
std::copy(path.cbegin(), path.cend(), std::begin(renameInfo->FileName));
THROW_IF_WIN32_BOOL_FALSE(SetFileInformationByHandle(hLegacyFile.get(),
FileRenameInfo,
renameBuffer.get(),
gsl::narrow_cast<DWORD>(renameBufferSize)));
```

The pattern regex now correctly disallows keybindings consisting of only
modifiers, modifiers not separated by "+", and unknown keys. Certain
shift+numpad combinations are also not allowed.
The description lists allowed key names in tabular format (assuming the
client renders \t correctly).
Add the option to set the cursor color as part of the color scheme.
This is very useful for light themes, where the cursor disappears unless its color
is set in the profile.
Related to issue #764, but doesn't fully resolve it.
## Validation
I tested this manually by creating a light color scheme, setting the cursor color
to black and setting the profile color scheme to the newly created color scheme.
I validated the cursor is black, then set the cursor color in the profile (to red)
and saw it trumps the cursor color from the color scheme.
If UseAcrylic is disabled, CTRL+SHIFT+SCROLL would enable it, without
having to change the setting in profile.json manually.
1. Set "useAcrylic" to false for the any profile in profile.json
2. Open terminal window for that profile.
3. CTRL+SHIFT+MouseScroll
Acrylic background opacity should change according to mouse scroll
