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.

Attempting to run when SURFACE_VIEW_FORMATS isn't successful,
so the alternative approach is to more gracefully report the
error.

Further constrain the hiding logic for key-down events, so that
we are less likely to hide for things ctrl-shift-c when the user
is mousing around and copy/pasting.
Also, consider CapsLock to be a modifier for this and other
similar purposes.

Don't fallback to some other serial.
In a new version of SCTK, it looks like the serial we pass should
be the serial from the time we entered the surface, rather than
the latest serial that we have.
In practice, this commit uses None for the serial which seems to
have better results, but may come back to haunt us until we upgrade
to the latest SCTK.

This allows for potentially listing multiple candidate cursor names,
like we do for x11, but doesn't add any.
Attempt to load default if our desired cursor is not found.

For eg: RU layout, CTRL-S shouldn't result in ы in the context
of a terminal.
The approach taken here is similar to kitty; when the key combination
doesn't produce a definitive composed output, and when any of
ctrl/alt/super are present, we treat the keypress as though it were
the same as the one from the system default keymap.
The result is that ctrl-c now works like ctrl-c and alt-b and alt-f work
like their latin counterparts.
Hopefully there are no downsides to this!

The main part of the problem is that NSWindow::isZoomed lies to us
sometimes.
This is a relatively gross workaround.
Add missing invalidation after setting the content size; that prevents
janky when dragging the window between monitors.
Removed some redundant Dimensions computation from that method; nothing
ever read it.

It's a little limited in the scope of its detection: we have a built-in
list of tiling WM environments and if the current one is on the list
then we set an appropriate value for this option.
The list currently has just a single entry.
