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.

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.

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.
