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.
This fixes direct scanout VRR. As direct scanout buffers are not part
of the swapchain, we would mistakenly union instead of subtract the damage
meaning it will just accumulate indefinitely.
The reason for this existing in the first place is for compositors that
might want to sidestep scene and commit their own buffers to the output.
In this case, scene could theoretically acknowledge that and update the
damage. Except, this really didn't work because WLR_OUTPUT_STATE_DAMAGE
would need to be defined which is optional. This patch also properly
acknowledges commits without damage.
In the use case of a weird compositor that might want to sidestep scene,
they can just trash the damage ring themselves.
Fixes: #3871
There were two problems with the old implementation:
1. wlr_scene_output_commit would bail early if a frame wasn't requested
and there was no commit damage, however commit damage could never accumulate
until rendering happens. The check was subtly wrong as a result.
2. Previously, we would fill the pending commit damage based on the
current state of the damage ring. However, during direct scanout, the
damage would accumulate which would mean we would submit damage from
previous frames even if we didn't need to.
This commit removes extra wlr_xdg_toplevel_set_parent() calls,
simplifies wlr_surface->wlr_xdg_toplevel conversion logic, makes related
structures store wlr_xdg_toplevel objects directly instead of
wlr_surface objects, and improves the code style.
Without this patch, a client calling handle.destroy() will trigger
an assert in libwayland due to a NULL pointer for the destroy handler.
Also implement a missing .destroy handler for the manager itself
and delay destruction of the manager resource from the .stop handler
to the .destroy handler.
