This changes the semantics of wlr_output_state. Instead of having
fields with uninitialized memory when missing from the committed
bitflag, all fields are always initialized (and maybe NULL/empty),
just like we do in wlr_surface_state. This reduces the chances of
footguns when reading a field, and removes the need to check for
the committed bitfield everywhere.
A new wlr_output_state_init() function takes care of initializing
the Pixman region.
This increases type safety, makes it more obvious that role_data
must represent the role object, and will allow for automatic
cleanup when the resource is destroyed.
This commit allows to make a role as not represented by an object,
which fixes calling role commit handlers for roles like cursor
surfaces.

If the set_cursor request is used with the same surface, don't call
cursor_output_cursor_reset_image(). That function sends
wl_surface.leave and can cause an infinite feedback loop with some
clients (submitting a LoDPI cursor when the surface leaves an HiDPI
output).
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3669
Currently, an icon surface's role_data is set manually to a struct
wlr_drag_icon, which is hacky, incorrect (as role_data is supposed
to be the surface's role object, and drag icons don't have them), and
will be disallowed by future changes.
Based on five calls:
wlr_render_timer_create - creates a timer which can be reused across
frames on the same renderer
wlr_renderer_begin_buffer_pass - now takes a timer so that backends can
record when the rendering starts and finishes
wlr_render_timer_get_time - should be called as late as possible so that
queries can make their way back from the GPU
wlr_render_timer_destroy - self-explanatory
The timer is exposed as an opaque `struct wlr_render_timer` so that
backends can store whatever they want in there.
read advances the file description offset, and requires the client to
ensure that it is reset appropriately before the next gamma ramp
submission. As there is no event to indicate that wlroots finished
processing the new gamma ramp, this can result in a race between the
client seeking in the file and wlroots reading its content.
Use pread with a fixed offset instead.

According to the protocol text, the popup will be immediately dismissed
when the grab is rejected. Because the grab can't be executed with a
destroyed seat, the popup is dismissed when one is provided.
Many issues here:
- wlr_output_cursor_set_buffer() takes a buffer already scaled for
the output, not a buffer with scale=1.
- wlr_output_cursor.{width,height,hotspot_x,hotspot_y} are in output
buffer coordinates.
- render_cursor_buffer() had hardcoded no-ops for scale and
transform, instead of using the cursor surface's.
Fixes: b64e7e88bf ("output: add output_cursor_set_texture()")
A client might update the cursor with the same wl_surface as
before, but with a different hotspot. Don't ignore such updates.
Fixes: 9c9e3f6263 ("cursor: ignore wlr_cursor_set_surface() with same surface")
This is to allow for compositors that want to be more implicit about
how their scene is organized. Such a compositor may want to walk up
at a certain scene node to find something such as a surface to focus on.
If a modeset contains a render format change, use that instead of
the current one stored in wlr_output.render_format.
This fixes render_bit_depth configuration not being applied without
a second modeset in Sway.
Some formats like sub-sampled YCbCr use a block of bytes to
store the color values for more than one pixel. Update our format
table to be able to handle such formats.
According to the spec the compositor should send scanout modifiers in
their respective device tranches, and all other texture modifiers
in the main tranche. Currently wlroots expects all modifiers to be
present in the last (i.e. "fallback") tranche, this removes that assumption
in the feedback compilation stage so that scanout modifiers for secondary
device can be advertised.
"The full-screen feedback parameters have two tranches: one with the
format/modifier pairs supported by the KMS plane, with the scanout flag
set in the tranche_flags event and with tranche_target_device set to the
KMS scan-out device; the other with the rest of the format/modifier
pairs (supported for texturing, but not for scan-out), without the
scanout flag set in the tranche_flags event, an"
