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 will become necessary when we switch away from scissoring. For the
time being, this cleans things up a bit and allows for a trivial
blending implementation for textures when that comes.
This commit allows to make a role as not represented by an object,
which fixes calling role commit handlers for roles like cursor
surfaces.

The kernel complains when the damage exceeds the FB bounds:
[73850.448326] i915 0000:00:02.0: [drm:drm_atomic_check_only] [PLANE:31:plane 1A] invalid damage clip 0 0 2147483647 2147483647
Make the DRM backend behave like the Wayland one and allow compositors
to damage (0, 0, INT32_MAX, INT32_MAX) to repaint everything without
needing to know the exact buffer size.

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.
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()")
We'll soon introduce a unified wlr_surface map event. Up until now, compositors
have been using wlr_xwayland_surface's map event to setup various wlr_surface
related listeners (e.g. commit). This will no longer be possible when that
event is moved over to wlr_surface. Introduce new events where the compositor
can add/remove wlr_surface event listeners.
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.
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.
This is implemented by a two-subpass rendering scheme; the first
subpass draws (and blends) onto a linear R16G16B16A16_SFLOAT buffer,
while the second subpass performs linear->srgb conversion, writing
onto the actual output buffer.
Goals:
- Extensibility: we need to be able to add new params to the calls
to render a texture/rect. For instance we'll need to add fences to
the render texture operation for explicit sync purposes.
- No implicit state: no more bind_buffer, begin, end.
- No matrices: these hurt Pixman and we don't need them.
- Clip regions for optimized damage repainting.
