The wlroots Wayland backend does not support gamma LUT application and
will currently fail to render anything if river commits a gamma LUT.
To fix this, test the state when applying a gamma LUT and fall back to a
state with no gamma LUT set if that fails.
This problem was revealed by 2e09b66 which flags gamma as dirty on all
outputs when they are enabled.
The X11 protocol uses 16 bit integers for width/height but we use
32 bit integers everywhere else in river. Make sure that values outside
the range of a 16 bit integer don't cause river to crash with an
assertion failure.
I think that coordinates outside the range of a 16 bit integer could
theoretically be reasonable with tiled high resolution displays in the
future. I doubt they ever get used in practice today but at the same
time we can't allow an errant layout generator to crash river.
We must clean up the user data of the wlr_surface for layer surfaces and
lock surfaces as fromSurface() may be called (e.g. by the idle inhibit
implementation) after the scene node has been destroyed but before the
wlr_surface is destroyed.
There is no FreeBSD tarball from ziglang.org and FreeBSD itself has not
yet updated their Zig package to 0.12.0. This commit should be reverted
when a good way is found to obtain Zig 0.12.0 for the FreeBSD CI.
This assert is incorrect if Xwayland is enabled and an Override Redirect
window steals the keyboard focus from the parent surface.
It also seems likely to be hit if a Wayland client attempts to use a
pointer constraint on a subsurface. I don't think a pointer constraint
on a subsurface is likely to work entirely correctly and I don't know of
any Wayland clients that try such a thing. We can't let them crash river
by trying though.
Currently if a second keyboard input device is created river will send
a wl_keyboard.leave event immediately followed by a wl_keyboard.enter
event. This serves no purpose and can confuse clients, in particular due
to fctix creating/destroying virtual keyboards on focus change.

Xwayland clients on outputs at negative positions don't currently
receive mouse events due to a bug in Xwayland. As a workaround, we
disallow negative output positions when Xwayland is enabled.

Currently if a client commits a geometry with a different x/y value but
does not change the width/height we might not update the clip
coordinates of the surface tree, potentially causing part of the surface
to be unintentionally clipped off.
To fix this, check for change in geometry x/y as well as width/height on
commit if the client is not currently part of an ongoing transaction.
Firefox for example it seems may respond to a configure non-atomically
with multiple commits:
1. commit new buffer and new geometry of a new width/height.
2. commit again with the same width/height but a new geometry x/y.
I don't think this is technically a bug but it doesn't seem like the
most efficient way to do things. I think this may also cause imperfect
frames. In any case, this should no longer cause river to crop off part
of firefox's surface.
It seems layer-shell clients such as waybar can commit bogus exclusive
zones larger than the width/height of the output. While this client
behavior is questionable at best, it must not cause river to crash or
otherwise misbehave.
Therefore, close layer surfaces causing the usable (not exclusive zone)
area of an output to be reduced below half of the width/height.
Also remove the redundant URL in the footer and the redundant
"General Commands Manual" text (scdoc adds that by default based on the
section it seems).
The correct way to do this would be to use the max-width css attribute,
but codeberg seems to strip that when converting markdown to html.
The new value of 600em looks almost identical to 50% on large screens
and looks a lot better on small (mobile) screens.
Currently if we disable an output due to a wlr-output-power-management
protocol request we do not update Output.lock_render_state properly.
This is fine if the output is also re-enabled using the
wlr-output-power-management protocol but causes an assertion failure
if it is re-enabled using wlr-output-management instead.
