This might "break" eg: pasting from apps that just use ATOM_STRING
and that happen to have utf-8 compatible text.
Ideally the get_text_property interface would expose the actual
text encoding in the returned data and allow the application to
"do stuff" with it.

Resolves a little bit of the awkward duplication of color types
between some of the crates by factoring them a little bit better.
This is prep for allowing specifying alpha for some colors
in the config.
This puts to final rest #478, wherein ligatured glyphs that span
cells would render portions of the glyph with the wrong fg color,
where wrong was usually the bg color and cause the glyph to turn
invisible when cursoring through the ligature.
The approach used here is to divide the glyph into 7 discrete strips
where each strip either intersects with the cursor, the selection, or
neither. That allows us to render each strip with the appropriate
foreground color.
This change simplifies some of the logic and allows some other code
to be removed, so that feels good!
As is tradition with these renderer changes, there's a good chance that
I overlooked something in testing and that the metrics or alignment
might be slightly off for some font/text combo. Let's see how this
goes!

This allows unicode_version to be respected again when rendering.
The updated emoji-presentation.sh script now highlights this slightly
better by putting `.` characters after the emoji; unicode version 14
emoji presentation will show the `.` in the 3rd column, while earlier
versions will show it in the 2nd column for glyphs that are sensitive
to the version.

This action causes the active workspace for the gui to change.
If the name is omitted a random name will be generated.
If the workspace doesn't exist, it will be be created.
The optional spawn parameter can be used to launch a specific
program into the new workspace; if omitted, the default prog
will be used.
The gui only supports a single active workspace. Switching workspaces
will repurpose existing gui windows and re-assign them to windows
in the new workspace, adjusting their size to fit those windows,
spawning new windows or closing unused windows as required.
The gui now exits when there are no panes in the active workspace,
rather than no panes at all.

When a dead key is composing, we gave no information about what was
composing. Contrast with Windows and macOS where we show the first
key in the composition as part of that state.
This commit makes an attempt to populate equivalent information.
It's a bit more complex with the xkeyboard stuff as there can be
multiple combining sequences and there's no guarantee that we can
show a meaningful label.
We try our best for the common case of a single dead key, and have
a probably reasonable fall back for other cases where we don't
other get that information.
This allows removing DeadKeyStatus::Holding.
lalt-` is technically a dead key combo, so we entered dead key
processing, then realized that
`send_composed_key_when_left_alt_is_pressed == false` and that
we should ignore the dead-key-ness of the combo, but returned
a composed result, which had the modifiers discarded.
The correct way to handle this is to signal that it wasn't
dead after all and to allow the main flow to build the KeyEvent
as normal.
We need 100% of the info for it to work correctly, so this commit:
* Exposes the keyboard encoding mode via the Pane trait
* Adds the scan code to the RawKeyEvent
* Has the GUI perform the encoding if the keyboard is set that way
* Removes the basic encoder from termwiz in favor of the gui level one
The net result is that we bypass the Pane::key_up/Pane::key_down methods
in almost all cases when the encoding mode is set to win32-input-mode.
There is now a config option: allow_win32_input_mode that can be
used to prevent using this mode.
refs: #1509
This commit causes the terminal to emit win32-input-mode encoded key up
and down events for a limited subset of keys When win32-input-mode is
enabled.
We limit them to keys where we know the VK key code equivalent,
and where those keys are either not representable (eg: modifier
only key events), or may generate ambiguous output (eg: CTRL-SPACE
in different keyboard layouts).
However, in my experiments, modifier only key presses confuse powershell
and cause it to emit `@`, so I've disabled that in the code for now.

When we translate a dead key, send the composed event immediately
and don't try to route the current key press via the IME.
Improve rendering when in the composing state: overlay the composing
text at the cursor position to show what the composing text would
look like, even though it hasn't been committed to the input stream
yet.

For Korean text input, pressing SHIFT and then typing in certain
keys begins a composition sequence. Our logic for when to route
via the IME got so distracted by ALT that it didn't consider SHIFT
and didn't send this sequence to the IME, so we'd fail to compose
those sequences.
While poking at this, I realized that we should treat this composition
similarly to dead keys, in that we can signal the term window to
highlight the cursor color and report that status.
There's some further work to do: the composing text should be rendered
by us. So far our IME integration assumes that the IME itself will
render over the top of our window, but for this particular input
it doesn't do that.

Since we now have RawKeyEvent and a sane way to indicate handling,
we don't need these any more, and it simplifies key dispatch to
remove them.

Pass down whether we are in a live resize to the gui layer, so that
we don't incorrectly assume that the scale has changed, and fight
with the window manager.
Built this on my mac: will need to fixup for windows and linux.

This moves the event dispatching into the keyboard processor,
which will allow for the processor to skip feeding an event
into the dead key/composition stuff if a key assignment is
handled.
It doesn't actually do that bit yet though, as the wayland
key repeat processing was a bit more involved and I wanted
to constrain the scope of this commit.
