Adds a cursor_hide_timeout config key (Option<u32> seconds) to
CosmicCompConfig. When set, the cursor is hidden after the configured
period of pointer inactivity and revealed again by any pointer event.
Touch input does not count as activity (no visible cursor to surface).
Implementation:
- Per-seat hidden flag, calloop timer token, and last-armed Instant on
CursorStateInner.
- notify_cursor_activity called from each pointer-related input branch
(motion, button, axis, tablet) resets the flag and reschedules the
timer; rapid successive calls are coalesced behind a 100ms throttle
so high-frequency mice don't churn the calloop timer source.
- On timer fire, the hidden flag is set, draw_cursor short-circuits to
an empty element list, and a render is scheduled. Active pointer
grabs (drags, resizes) suppress the hide.
- Config reload arms or cancels the timer immediately; None as the
configured value collapses the cancel path into the same function.
Closes#2231.
Drafted with Claude (Anthropic); reviewed and tested by the committer.
Everything implementing `AsGlowRenderer` implements `Renderer` and various
other traits, and by making `AsGlowRenderer` depend on these trait,
things requiring `AsGlowRenderer` can avoid listing those traits as
well.
Looks like implied trait bounds still won't work for the
`Self::TexutureId` and `Self::Error` requirements? So those are not
included here.

The important change here is that we now apply the additional damage
first, instead of using `.extend()` to add it after other elements. This
is important since `OutputDamageTracker` will ignore our damage elements
if there are behind an element with an opaque region.
This also makes things a bit simpler, especially `take_screencopy_frames()`,
which no longer needs a mutable references to extend then truncate.
The implementation of `OutputDamageTracker` isn't entirely clear, but as
far as I can tell this is intended to work, and it seems to work in some
testing.
This doesn't change much, since the Smithay implementation is based on
the `cosmic-comp` version, but made more generic. We provide our own
implementation for our workspace capture protocol, but otherwise Smithay
handles the boilerplate now.
This should not cause any change in behavior.
