From the event description:
This event indicates that the output power management mode control is no
longer valid. This can happen for a number of reasons, including:
<...>
- The output disappeared
This swaps the argument order of wlr_surface_accepts_touch() and
wlr_surface_accepts_tablet_v2(), putting the wlr_surface argument first
as should be the case for functions namespaced with wlr_surface_*.
We were relying on the fact that we wouldn't paint anything on top
of the black background in the region of a black rect. However
when fractional scaling is used the repaint region might get
expanded to nearby pixels by scale_output_damage(). As a result
the neighbour scene nodes might leak into the skipped black rect's
region.
Avoid this by using this optimization for bottom-most black rects
only when fractional scaling is used.

If we need to apply a color transform to rendered content, we will not
be able to use direct scanout. Explicitly skip it to not accidentally
show frames lacking the color transform.
The DRM backend's set_cursor function always return true if the
buffer is NULL. If using a NULL cursor's buffer on startup, the
wlr_output_cursor will be marked as a hardware cursor. If the
cursor later gains a non-NULL buffer and the DRM backend rejects
that buffer, the cursor will remain marked as a hardware cursor,
despite the backend not displaying it as such. As a result, the
cursor will not be displayed at all. Fix this by always resetting
the hardware_cursor field in output_cursor_attempt_hardware().
Instead of having separate getters for shm formats and DMA-BUF
formats, use the same pattern as wlr_output_impl.get_primary_formats
with a single function which takes buffer caps as input.
Clients may, for example, commit an exclusive zone larger than the
output dimensions. Compositors must handle this gracefully, which likely
requires more work on the compositor side but returning a usable area
with negative width or height in wlr_scene_layer_surface_v1_configure()
is nonsensical.
When a wlr_gamma_control client calls set_gamma, we allocate a LUT based
on the value returned from wlr_output_get_gamma_size at the time of the
call.
If the output is off and has no CRTC, such as if gamma changes in the
background while a display is disabled for idle reasons,
wlr_output_get_gamma_size returns 0. This leads to a zero-sized table,
which the drm backend interprets as a request to reset gamma tables to
their default.
Store the gamma size when the gamma control was created. Even if the
size changes, this is the size the client was sent and uses to create
the LUTs it sends.
The surface argument is only used to obtain a wlr_seat_client and
semantically makes no sense. The wl_touch.cancel event applies to all
touch points and all surfaces of a client.
I decided to make the functions accept a wlr_seat_client rather than a
wl_client as it is directly available in the wlr_touch_point struct and
simplifies the implementation.
Previously, cases when a viewport source box was updated without attaching
a buffer weren't checked for correctness properly because the state's buffer
would be NULL. Use wlr_surface_state_has_buffer() instead.
