Since headless and wayland-without-presentation-feedback were firing
present inside their commit impls, present was getting fired before
commit, which is cursed. Defer this with an idle timer so that commit
handlers can run before present handlers.
These states would be set if output_init is invoked with a enabled state.
This would make frame_pending == true which means wlroots will ignore
any further frame events and the compositor will appear dead.
Up until now, frame/present events were only triggered when the
user submitted a buffer. Change the wlr_output API so that these
events are triggered when any commit is applied on an enabled
output.

It's still not possible to commit while a page flip is pending in DRM,
but we don't need to enforce that here and allowing it through the
common interface can be useful for other backends.
This decouples commits from frame scheduling, which is going to make the
new frame schedulers easier to implement.
When setting a custom mode current_mode will not be reset. That means
that next time the compositor tries to reset back from the custom mode,
it will compare against the stale current_mode and unset
WLR_OUTPUT_STATE_MODE erroneously.
When a wlr_output add to wlr_output_layout, wlr_cursor will create
wlr_buffer of xcursor for the wlr_output, this behavior depends
wlr_renderer of wlr_output, using assert to ensure renderer is
initialized before wlr_output_layout_add and wlr_cursor_set_buffer/
wlr_cursor_set_xcursor.
This function takes a pointer to memory with a hardcoded format
and many parameters to describe the pixel buffer.
wlr_output_cursor_set_buffer() can be used instead.
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.
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()")
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.
The Wayland, X11 and headless backends don't really care about the
cursor size. We were picking a size identical to the texture size
in that case. This is incorrect for LoDPI cursor textures on HiDPI
outputs: in that case, we need to scale up the cursor texture.
Fixes the cursor being chopped off under the Wayland backend with
scale > 1.
Add a src_box state field. Use the SRC_* KMS props in the DRM
backend, reject the layers in the Wayland backend (for now, we can
support it later via viewporter).
wlr_output is not well-suited to checking whether direct scan-out
is happening or not. Compositors may want to use their own external
swapchains, for instance.
Additionally, ab7eabac84 ("output: leverage
wlr_output_configure_primary_swapchain()") makes it so
output_basic_test() is called before the output swapchain is
initialized, resulting in false positives.

This allows callers to set a destination size different from the
buffer size to scale them.
The DRM backend supports this. The Wayland backend doesn't yet
(we'd need to wire up viewporter).
