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.
If multiple consecutive transaction timeouts occur it is possible for
the SSD borders to become temporarily desynchronized with the size of
the rendered surface.
This is especially noticeable during interactive resize of mpv.
For details on cause/fix, see the new comment in the code.
This fixes a possible assertion failure in Cursor.updateState() when
trying to start move/resize of a xdg toplevel with the timed_out or
timed_out_acked configure_state.
This also generally improves the UX of transaction timeouts as all
state except for the size change is now applied immediately.
There is not any pointer emulation for tablet tool input. This means
that only clients implementing the tablet-v2 protocol will be able to
process tablet tool input.
Tablet pad support is TODO
This assertion does not consider that a view may be visible on an output
despite no view on that output having focus due to a differnt output
currently having focus.
I don't see any clean way to fix the assert, so just remove it.
