This serves as a bad example: compositors should validate serials from
events instead. Also, the current implementation segfaults if
focused_surface is NULL.
After a connector scan, new connectors might have appeared and old ones
gone away. At this point, old CRTC allocations are already gone, while
new allocations are not yet needed. Skip the call.
If a surface with an existing buffer has a syncobj surface state created
without committing a new buffer with associated timelines, callers will
see the surface as having a syncobj state and may try to use it, but
calling the signal_release_with_buffer helper at this time will assert
on the lacking release timeline.
As this is a valid situation, remove the assert and replace it with an
early return so that callers do not need to explicitly check for the
presence of valid timelines.

Color transform can have multiple types and these different types
want to store different metadata. We previously stored this metadata
directly on wlr_color_transform even for transforms that don't use it.
Instead, let's take the prior art from wlr_scene where each scene node
is built on a base node. Notice how wlr_color_transform_lut3d now has
a `struct wlr_color_transform base`. This is advantageous in multiple
ways:
1. We don't allocate memory for metadata that will never be used.
2. This is more type safe: Compositors can pass around a
struct wlr_color_transform_lut3d if they know they only want to use a
3d_lut.
3. This is more scalable. As we add more transform types, we don't have
to keep growing a monolithic struct.
The spec for VkMemoryPropertyFlagBits says:
> device coherent accesses may be slower than equivalent accesses
> without device coherence [...] it is generally inadvisable to
> use device coherent or device uncached memory except when really
> needed
We don't really need coherent memory so let's not require it and
invalidate the memory range after mapping instead.

A struct wlr_xdg_toplevel_configure is passed in with the whole
state. This makes it a lot clearer that the size and WM state are
always sent to the client.
The page_flip can be destroyed, but it is unconditionally accessed later
on when setting present_flags. Fix this by simply setting the
present_flags before the page_flip gets destroyed.
It was completely wrong: according to the protocol, the effective
geometry is only updated on commit time if there pending state has
new state from xdg_surface.set_window_geometry or
xdg_surface.set_window_geometry has never been sent at all.
This commit adds wlr_xdg_surface.geometry which correctly matches the
effective window geometry and removes now-useless
wlr_xdg_surface_get_geometry().
It seems that some scene compositors want to avoid wlr_scene_output_commit
and use the lower lever wlr_scene_output_build_state. However, build
state does not early return if a frame is not needed so compositors will
implement the check themselves. Let's add a helper function that compositors
can use to implement the check.
Technically pending_commit_damage is a private interface, so this lets
compositors not interface with private interfaces to implement the check.
