...in wlr_scene_layer_surface_v1_configure()
Reproduce bug with waybar by setting `"margin": 5,`
in ~/.config/waybar/config. It will result in the right edge of the panel
extending outside the edge of the output.
The bug can also be reproduced with gtk-layer-demo by anchoring
left/right/top/bottom and setting respective margins

Before calling wlr_output_impl.{test,commit}, perform a cheap
comparison between the current and candidate state. Unset any
fields which didn't change.
This refactors output_ensure_buffer() to not mutate the state passed,
making the previous subtle behavior much more explicit.
Fixes: d483dd2f ("output: add wlr_output_commit_state")
Closes: #3442
Replace them with wlr_signal_emit_safe, which correctly handles
cases where a listener removes another listener.

See the discussion at [1]: there's no easy way to fix libwayland-cursor
without a new API. Sending the error for other roles will prevent the
same client bug from appearing elsewhere.

This commit ensures that outputs that weren't created by the output
layout helper aren't destroyed on the output layout change.
Consider the following piece of logic:
// struct wlr_output *o1, *o2;
// struct wlr_scene *scene;
// struct wlr_output_layout *layout;
wlr_scene_attach_output_layout(scene, layout);
wlr_output_layout_add_auto(layout, o1);
struct wlr_scene_output *so2 = wlr_scene_output_create(scene, o2);
wlr_output_layout_move(layout, o1, 100, 200);
// so2 is invalid now
Since 5e0ef70cc0 ("seat: Create inert objects for missing capabilities")
wlroots can create inert seat objects when the capability is currently missing
for the client but it had the capablity before. The client hoever will happily
handover the wl_pointer resource to the relative_pointer implementation,
creating a NULL pointer dereference when trying to access the seat_client which
is set to NULL for inert objects.
Since the protocol does not contain an error for such requests, we hand out an
relative_pointer handle with the seat set to NULL.
We also need to check whether there is an associated seat in
send_relative_motion and need to tweak the destroy notifier in case no seat is
available.
This way we can hand out a valid relative_pointer resource and don't crash the
compositor when trying to access an inert seat pointer resource in
relative_pointer.

[1] has changed wlr_drm_format to remove the assumption that
MOD_INVALID is always implicitly enabled. MOD_INVALID is now part
of the modifier list just like any other modifier.
The patch adding support for linux-dmabuf-v1 feedback has been
written a lot of time before [1], and hasn't been updated accordingly
when merged. This results in MOD_INVALID being advertised twice [2] and
other index bugs.
Fix these issues by removing special-casing for MOD_INVALID.

This allows the make/model/serial to be NULL when unset, and allows
them to be longer than the hardcoded array length.
This is a breaking change: compositors need to handle the new NULL
case, and we stop setting make/model to useless "headless" or
"wayland" strings.
This will display red translucent rectangles on the screen regions that
have been damaged. These rectangles will fade out over the span of 250
msecs. If the area is damaged again while the region is fading out,
the timer is reset.
Let's also disable direct scan out when this option is enabled, or else
we won't be able to render the highlight damage regions.
After cancelation we destroy the touch points associated with this
surface as the Wayland spec says:
No further events are sent to the clients from that particular gesture.
Touch cancellation applies to all touch points currently active on this
client's surface. The client is responsible for finalizing the touch
points, future touch points on this surface may re-use the touch point
ID.
