Storing the frame pacing output in a per-scene and per-surface
struct doesn't play well with multiple scenes. outputs_update is
only triggered for outputs the scene knows about, but operates on
all outputs the surface has entered regardless of the scene. Thus
leaving an output on one scene will not refresh the frame pacing
output on other scenes, and these other scenes will operate with
a stale frame pacing output. The surface will not receive any more
wl_surface.frame done events.
This also avoids keeping a dangling pointer around when the frame
pacing output is destroyed but the output isn't added in the scene.

The stop handler disables the output. However, the same source can
be captured multiple times in parallel. In that case, stop might
be called while another capture session is still ongoing.
Only disable the output if the last session is stopped.
Before this patch, when a surface became occluded on all outputs,
we'd reconfigure it with a base configuration (scale set to 1,
transform set to NORMAL, image description set to gamma 2.2/sRGB).
As a result, when quickly hiding a toplevel and showing it again,
the client would render to switch to the base configuration, then
render again to switch to the output configuration.
Avoi this needless back-and-forth by retaining the last sent
preferred configuration when a surface leaves all outputs.
This avoids hardcoding lists of TFs/primaries in compositors.
I've considered adding wlr_color_manager_v1_create_with_renderer()
instead, but I'm worried that some aspects of the options struct
don't really depend on the renderer, but on the compositor. Such
things are features and render intents.
I've considered returning a const array, but this would tie our
hands if we want to make the renderer advertise the set of
TFs/primaries it supports, instead of having a single flag gating
all of them.
This is needed for cases where the touch operation goes over a region
where no surfaces are present. In this case, we'd want to notify the
touch grabs (for example DnD grabs) that no focus is currently focused.
If the client application is composed of multiple components and they
bind the manager global separately, choosing a single toplevel resource
with wl_resource_find_for_client() may result in a component only seeing
unknown toplevel handles from another component.
Maybe we should track which toplevel handle resource originate from
which manager resource so that a component never sees toplevel handles
resources from another component, but it's too annoying to implement.
Currently it is possible to crash a wlroots compositor by setting any
axis source other than 0 and sending an axis event in the HORIZONTAL
direction from wlr_virtual_pointer since the axis source is only set on
the first axis.
This then hits the assert in wlr_seat_pointer.c:332.
Fix by always setting the source on all axis.
Fixes incorrectly rejecting scanout for gamma2.2 buffers when the output
has no image description set. This happens on `hdr off` mode on sway.
Also refactor the scanout check into its own function while at it to
make it easier to follow.
We were incorrectly doing comparison with `!= 0` to detect non-sRGB
tf/primaries. Since these enums are bit flags, the default sRGB values
are 1, not 0, so sRGB buffers were incorrectly rejected.

When attaching more than one cursor to wlr_output, the first one
will pick the output's hardware cursor, then for the second one
output_set_hardware_cursor() would fail (since the hardware cursor
was already taken), but we still ended up resetting the current
hardware cursor (by calling output_disable_hardware_cursor() below).
As a result only the second cursor would be displayed.
To fix this, move the current hardware cursor check to the caller.

Upon leasing, the wlr_drm_lease_connector_v1 will be automatically clean up by the wlr_output
destroy handler. There is no need for the wlr_drm_lease_manager to keep track of leased connectors.
