Does what it says on the box: is true when the compositor is shutting
down.
When we begin to use universal planes, we need divergent destruction
paths. With universal planes, the drm_planes are created at backend
initialisation time, and destroyed with the backend. However, without
universal planes, we create per-output drm_planes to hold the
primary/scanout and cursor planes, whose lifetime is tied to the output.
We will use the new shutting_down flag to determine if output
destruction is hot-unplug or compositor shutdown, and make a decision on
whether or not to destroy the special planes.

zwp_linux_dmabuf_v1 allows clients to pass an explicit pitch for each
plane, but wl_shm only takes a single pitch parameter; the pitch for
secondary planes must be inferred.
Multi-plane sub-sampled textures have partial width/height, e.g.
YUV420/I420 has a full-size Y plane, followed by a half-width/height U
plane, and a half-width/height V plane.
GStreamer's waylandsink - the only user of wl_shm YUV formats - expects
the implementation to follow the example of Xv and implicitly divide the
pitch for secondary planes by the subsampling factor. gl-renderer was
not doing this, and instead just using the (larger) stride provided by
the client for all planes in the buffer.
Fix gl-renderer to divide pitch by the subsampling factor when uploading
from subsampled SHM buffers into GL textures, also dividing co-ordinates
when doing offset partial uploads.

the output area remaining black as partial GL texture uploads would
practically never update the texture. If the parent compositor was

The wayland-backend with --sprawl is one way to trigger
wayland_output_create_for_parent_output(), which intends to find a mode
from the parent mode list and use it. Calling wayland_output_set_size()
initialized an embedded struct weston_mode and inserts that into the
mode list. Then the assignment output->mode = *mode; corrupts the
mode_list by overwriting the link entry. This leads to an endless loop
in bind_output() in compositor.c.
Fix this by manually doing the setup that wayland_output_set_size() did
and do not call it.
As a side effect, it now relays the parent compositor's physical output
size to our own clients. It no longer smashes the refresh rate either.

Calling wl_display_roundtrip() from within a Wayland event handler means
we will re-enter event dispatch, that is, it will lead to recursive

unexpected code paths: the first event handler function has not returned
when other event handler functions may get called. In this particular
case it maybe didn't hurt, but it's still a fragile pattern to use.
Replace the wl_display_roundtrip() with a manual sync callback to do the
work.
This does not break the wayland-backend initialization sequence, because
sprawl_across_outputs was set only after the roundtrip to ensure
wl_registry globals have been received so the code would not have been
hit anyway, and weston_backend_init() also has a second roundtrip that
ensures the per wl_output events have been received before continuing.
For wayland-backend output hotplug the change is insignificant because
it will only delay the output creation a bit, and the parent outputs are
