The vertical alignment is wonky, and some glyphs have the wrong
aspect and are missig colors. eg: the watermelon glyph in Noto Color
Emoji (U+1f349).
Turn this off by default, and skip loading fonts that have svg by
default.
The approach we were using previously was to ask macOS for the fallback
font list, but it didn't include the correct fonts for certain
codepoints.
Switch to using an alternative API that asks macOS which font to use for
a specific codepoint.

This is primarily to improve the chances of displaying an arbitrary
image without resorting to additional external tools, that may be
difficult or impossible to install.

otherwise, the termwiz line reader can become confused and
fail to recognize key presses like `(` which have SHIFT and LEFT_SHIFT
set.

Neither of these understand image protocols, and both are
an additional processing layer between the application and
wezterm.
This commit detects and wraps OSC sequences in tmux's passthru
sequence so that the data is passed on to wezterm rather than
elided from the data stream.
For image protocols in both tmux and conpty, work a little
smarter and explicitly move the cursor position to the same
location that wezterm would move it to. That prevents the
display from being as mangled by tmux/conpty due to a diverging
understanding of the cursor position.
The logic isn't perfect, and can result in the x-coordinate
being incorrect, and this won't work with the new --position
argument either in its current state, without adding a lot
of complexity to deal with scrolling and relative and absolute
positioning handling.
To facilitate that, a new termwiz Terminal trait method has
been added to probe the terminal name, version, cell and pixel
dimensions. It's not pretty.

Feels safest to do this until we can make a smoother fallback
experience for webgpu.
I will revert this after tagging the release so that nightly
runs webgpu by default.
Relocate the helper function to mux-server-impl and have both the GUI
and the mux server call it at the appropriate times.
Introduce default_mux_server_domain which is used instead of
default_domain in the mux server. This is to avoid recursive
cycles when starting up the mux; we don't want the default
domain to be a unix client that connects to our selves because
we'll try to connect to ourselves, then in act of handling that
spawn in the default domain and try to connect to ourselves and
repeat.

This is fixing a regression introduced by the fix for #2845.
The resolution for this is relatively straightforward, but took a bit
of effort to plumb.
Previously:
* CTRL/ALT/SUPER-modified keys with no explicit expansion would end
up just taking the US layout version of the key. That worked well
for the intended problem with non-latin layouts, but for eg: German
layouts it caused expansion to totally the wrong thing
Now:
* CTRL/ALT/SUPER-modified keys which effectively expand to non-ascii
text (eg: cyrillic "Es") now take the equivalent key press from the
US layout (which would be "c" in the "Es" case). For European
layouts this heuristic seems to avoid unexpected effects, but could
do with some validation from native users.
To support this, the xkb code splits the `Keyboard` struct out from
some of the higher level logic and introduces a `KeyboardWithFallback`
struct that is built out of the user-selected keyboard layout, and
the fallback keyboard. Now the fallback keyboard is fed the same
key inputs as the selected keyboard to correctly model the key
combinations.

ssh connection or host authentication errors would not be displayed
when the config was in its default exit_behavior=Close state.
This commit introduces some plumbing to allow a pane to override
the effective exit_behavior value, so that ssh sessions can now
rewrite it to CloseOnCleanExit while they are in the process
of connecting.

Given a sequence like this, where the `ESC [ K` sequence is
emitted at the last column when wrap_next=true:
\u001b[47;30m 17:24:50 \u001b[0m\u001b[K
rather than treating the column as out of bounds, we'd clear the
final cell.

Avoid a "flash" of a single black but likely overly stretched and
awkwardly interpolated frame while we wait for big/animated/complex
images to load and decode.
For corrupt images, or images with an incorrect or typo'd filename in
the config, this prevents us from punting and just showing a transparent
background instead of something reasonable.
There were a couple of layers of issue here:
* In the ImageDataType::decode method, we didn't detect and do something
reasonable when the decoded image had 0 frames, later leading to
a panic in glyphcache when trying to index frame 0 of an empty vec.
* We shouldn't have been using ImageDataType::decode for window
background images
* Make the fallback/placeholder black rather than fully transparent
in the more modern decoder thread routine that we use for image
decoding at the gui layer.
