This is needed by drm_output_fini_egl() to be able to retrieve the
backend out of the drm_output on the shutdown path of the compositor.
Both the remoting plug-in and the pipewire plug-in are users of the
drm-virtual API and as such they would trigger a crash when shutting
down the compositor, as we're not setting up any backend whatsoever.

When a view is destroyed then the views of subsurfaces remain until the view
list is rebuilt for the next repaint.
During that time view->parent_view contains an invalid pointer and weston will
crash when it tries to access the view.
This happens for a surface with subsurfaces with views on two different outputs
with the ivi-shell:
When the surface is destroyed then the destroy handler of the ivi-shell
(shell_handle_surface_destroy()) may be called first. It will (indirectly)
destroy the view of the main surface with weston_view_destroy().
Next the surface destroy handler of the subsurfaces
(subsurface_handle_parent_destroy() is called. It will unmap the first view of
the subsurface. Here weston_surface_assign_output() is called which tries to
find the output of the second view and accesses the now invalid
view->parent_view in the process.
There are probably other ways to trigger similar crashes.
To avoid this, clear view->parent_view when the parent view is destroyed.

The pixel format stored in backends->format[0] is effectively looked up
via pixel_format_get_info(DRM_FORMAT_ARGB8888). Reuse that instead of
looking up the same via pixel_format_get_info_by_pixman(PIXMAN_a8r8g8b8)
in multiple places.
There are still two instances of hard-coded CAIRO_FORMAT_ARGB32 in
wayland_output_get_shm_buffer() that currently can not be obtained from
pixel_format_info.

Starting with commit 4cde507be6 "backend-drm: fix plane sorting" the
plane list will have a descending order of the planes rather than ascending.
This reversed order had the side-effect of exposing the fact that we
don't set-up a plane index when creating the drm_plane using the DRM
virtual API. Without settting a plane index for that drm_plane we
effectively overwrite the plane index which has the 0 (zero) entry.
This wasn't an issue before commit 4cde507be6 "backend-drm: fix
plane sorting" as it seems we never picked up that plane index as
being a suitable one due to the fact that those were assigned to primary
planes, but after that commit, the cursor plane will be one getting
the 0 (zero) plane index.
Finally, this would trip over because we attempt to place a (cursor)
view on a primary plane (where it would've normally be a cursor
plane) and we end up with no framebuffer ref.
This is fixed trivially by assigning a plane index, different than the
ones already created by create_spirtes().

Every shells have an implementation of weston_desktop_api structures.
It includes some callbacks to listen to xdg_surface signals. Committed callback
is one of them.
Currently, the xdg_shell don't invoke the weston_desktop_api->committed
callback when the xdg_surface is initial stage or no surface content.
In the case: the client attached a null buffer after the valid buffer,
the shell isn't going to invoke to xdg_surface committed, and don't know
the surface is disappeared. If the surface is fullscreen, we will get
a black background on the screen until a new valid frame come. That
should not happen.

Possibly the least useful place to use this, as the input comes directly
from pixman rects, and the output is more complicated than usual, but
I guess consistency counts for something.
There is some small benefit in switching to weston_matrix_transform_coord

All through weston we have code that passes int x, y or
float x, y or wl_fixed_t x, y pairs. These pairs are frequently
converted to/from wl_fixed_t and other types.
We also have struct vec2d and struct weston_geometry which also
contain coordinate pairs.
Let's create a family of coordinate vector structures for coordinate
pairs and use it anywhere we sensibly can.
This has a few benefits - it helps remove intermediate conversion
between fixed/float/int types. It lets us roll the homogenous
coordinate normalization bits into helper functions instead of
needing them open coded throughout the source.
Possibly most importantly, it also allows us to do some compile time
validation of what coordinate space we're working in.

One variant is used when a view is being positioned relative to a parent,
the other is when the view is being given an absolute position in the
