This is a second copy of the same assert that was removed in the last
commit. It should have been removed by that commit as well but was
overlooked.

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.
(cherry picked from commit 5d1fc034bc6aedc340671d5de76add308effd2e8)
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.

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.
(cherry picked from commit 9bbd34a0e31b6d429df2d39a59d8990a9585e186)
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.
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.
Also clean up this code a bit, it's no longer necessary to split these
one line functions out into separate files as Zig's conditional
compilation support has improved since these functions were originally
written.
This field being nullable at all is code smell. I think what needs to
happen here long term is for a proper separation of "window management
output" and "physical output" as concepts and integration outputs into
the transaction system.
That's a much larger change and I don't want to cause that amount of
code churn just before a release though.
I have managed to crash river (because the relevant assertion was wrong)
on this using fcitx5 (5.1.8) and anthy with the following sequence of
key events on a physical keyboard (every line followed by releasing
everything):
super-; (my shortcut to enable anthy)
shift-letter (fcitx doesn't release shift on its virtual keyboard)
escape
shift (fcitx sends another press event)
The failure to release shift is not the only weirdness happening, but
it's what eventually lead to the assertion failure.
This makes tablet tool cursors visually distinct from pointer cursors by
default. Client may of course continue to set custom cursors for tablet
tools if they have focus.
Also fixes a custom cursor set by a client persisting after the tablet
exits the client's surface until proximity out.
This was dropped from 200ms to 50ms in 4a65af66. However 50ms seems
to be a bit too short in practice. I often hit ugly frame imperfection
do to timeouts when toggling mpv between a small floating window and
fullscreen for example, even on a relatively beefy desktop computer.
This only happens while the video is playing in mpv, not while it is
paused. I believe this is due to mpv ignoring the compositor's hints for
when to render a new frame entirely while playing a video. It instead
renders at the framerate of the video being played, even if the
compositor requests a change in size. This isn't great but seems
unlikely to change [1].
Overall, hitting 100ms timeouts subjectively doesn't feel anywhere near
as sluggish as hitting 200ms timeouts and offers better frame perfection
than 50ms timeouts in at least this one example, there are bound to be
others.

Currently we can hit an assertion failure in the putNoClobber() call in
response to the down event since we fail to handle the cancel event.
This commit fixes that issue.
Currently we only support interactive move/resize with the pointer,
touch and tablet tool support are TODO.
Validate the serial here to ensure we don't start a pointer move/resize
in response to the client attempting to start a move/resize with
touch/tablet tool.
This fixes an assertion failure that the pointer's cursor is not hidden
during move/resize, which is how the issue was discovered. Another win
for assertions :)
Sensitive Wayland protocols such as wlr_screencopy and wlr_data_control
(clipboard managment) are now blocked by default inside security
contexts (e.g. flatpak 1.15.6 or later).
User configuration of the allowlist/blocklist is TODO.
