A compositor will not send a frame callback for our main window if it
is fully occluded (for example, by a fully opaque overlay...). This
causes the overlay to stuck.
For regular buffers, it _should_ be enough to *not* hint the
compositor it's opaque. But at least some compositor special cases
single-pixel buffers, and actually look at their pixel value.
Thus, we have two options: implement frame callback handling for the
overlay sub-surface, or ensure we don't use a fully opaque
surface. Since no overlays are fully opaque by default, and the flash
surface is the only one that can be configured to be
opaque (colors.flash-alpha), and since adding frame callback handling
adds a lot of boilerplate code... let's go with the simpler solution
of
Unsure if the protocol imposes a limit (haven't found any
documentation), or if the issue is in the libwayland implementation,
or wlroots (triggers in at least sway+river).
The issue is that setting a too long app-id causes the
compositor (river at least) to peg the CPU at 100%, and stop sending
e.g. frame callbacks to foot.

From the specification:
The Enter, Tab and Backspace keys will not have release events
unless Report all keys as escape codes is also set, so that the
user can still type reset at a shell prompt when a program that
sets this mode ends without resetting it.
Closes#1892
When building foot with pgo under gentoo's portage, LLVM tried to
generate profile data files directly under system root, triggering
sandbox violation and causing build to fail. Setting this envvar fixes
the issue by explicitly specifying profiling data location.

It appears to be slightly more up-to-date with recent Unicode
versions.
In particular, it handles the new "Symbols for Legacy Computing
Supplement" block, introduced in Unicode 16.
Closes#1865
This fixes flickering when foot is forced to double-buffer (e.g when
running under KDE, or smithay based compositors).
Since the damage region isn't updated, the sixel images aren't
included in the memcpy that is done to transfer the last frame's
updated regions to the next frame.
As a result, every other frame will have the sixels, while the others
don't.
Closes#1851
