entries for each possible RGB triplets.

Add VGEM to the Linux image that runs in the CI. There are tests that we
plan to add in the future that need this.
This brings a complication, as we already have VKMS in the image. The
order in which DRM devices are loaded is not always the same, so the
node they receive is non-deterministic. Until now we were sure that VKMS
(the virtual device we use to run the DRM-backend tests in the CI) would
be in "/dev/dri/card0", but now we can't be sure. To deal with this
problem we find the node of each device using a one-liner shell script.
This commit also updates the documentation section that describes
specificities of DRM-backend tests in our test suite.

Test different scenarios where child subsurfaces of unmapped
subsurfaces would get mapped. This test will fail in various
ways without the commit
"libweston/compositor: Do not map subsurfaces without buffer"
Also try to test potential regressions of that patch.
Signed-off-by: Robert Mader <robert.mader@collabora.com>
We can end in `subsurface_committed()` in different scenarios
without the surface having an attached buffer. While setting
the mapped state to `true` in that case doesn't matter for
that (sub)surface itself, it triggers its own child subsurfaces
to get mapped when they shouldn't.

Zoom is a neat trick, but in its current form it's very hard to test
and maintain.
It also causes output damage to scale outside of the output's boundaries,
which leads to an extra clipping step that's only necessary when zoom
is enabled.
Remove it to simplify desktop-shell and compositor.

Changing `wl_surface_damage()` to `wl_surface_damage_buffer()`
should not have an effect on the existing tests.
The new test will fail without the commit
"libweston/compositor: Cache buffer damage for synced subsurfaces"
Signed-off-by: Robert Mader <robert.mader@collabora.com>
The spec states:
> Because buffer transformation changes and damage requests may be
> interleaved in the protocol stream, it is impossible to determine
> the actual mapping between surface and buffer damage until
> wl_surface.commit time. Therefore, compositors wishing to take both
> kinds of damage into account will have to accumulate damage from the
> two requests separately and only transform from one to the other after
> receiving the wl_surface.commit.
For subsurfaces in sync mode, arguably the same is the case until the
cached state gets applied eventually. Thus, in order to keep complexity
to a sane level, just accumulate buffer damage and convert it only
when the cached state gets applied.
This mirrors how other compositors like Mutter implement cached damage
and what the spec arguably should demand.

In multiple output cases, finding the succesor from the inactive layer
might result in picking the wrong view when there are multiple views
being stacked in the inactive layer. This adds two additional checks to
favor views on the same output as the one being destroyed/removed.

This adds an additional check to make sure the current focus surface
is on the same output as the surface that is going to be activated.
This is necessary in order to avoid placing the currently focused one in
the inactive layer, which shouldn't happen in situations where the new
surface is going to be placed on a different output than the currently
focused one.

Some applications would set-up the app_id after the initial commit
(without a buffer) which is too late to correctly assign the application
to the corresponding output set-up in the configuration file.
This patch fixes that by checking one more time, after a buffer has been
attached, if indeed there's an output with an app_id set.
Fixes: #469

These formats are useful because they are often easier to produce
on CPU than half-float formats, and abgr16161616 has both >= 10bpc
color channels and adequate alpha, unlike abgr2101010.
The 16-bpc textures created from buffers with these formats require
the GL_EXT_texture_norm16 extension.
As WL_SHM_FORMAT_ABGR16161616 was introduced in libwayland 1.20,
update Weston's build requirements and CI.
The formats also needed to be registered in the pixel format table,
and defined in a fallback path if recent libdrm is not available.

We just copy the SHM buffer straight into a separately-allocated GBM BO,
so no need to take a reference on the buffer itself or keep it from
being released.
All drm_output_try_view_on_plane really does at this point is to call
the prepare_*_view function for the requisite plane type, and take a ref
on the weston_buffer from the client. Given that we don't need to keep
the client buffer alive, we can short-circuit
drm_output_try_view_on_plane, and instead just call
drm_output_prepare_cursor_view directly when we have a cursor plane.
This also makes it easier to just remove drm_output_try_view_on_plane in
following patches when we merge the overlay/scanout plane path into one.
Doing so gives us two clearly-separated paths: one for copying a SHM
client buffer into a cursor, and another for directly scanning out
client content.

For views which cover the entire output, we always attempt to place them
on the primary plane, to avoid a situation where we place a fullscreen
view into an overlay plane and then have to disable the primary plane,
which doesn't always work.
Move this check earlier, so we don't consider overlay planes to be
candidates for fullscreen views. This check should be changed in future
to only filter for opaque views, but that's for another time.

When we introduced support for variable zpos, we did so by filtering the
list of acceptable planes and then creating a separate zpos-ordered
list. Now that the planes are already zpos-sorted in the backend list,
and we have more early filtering, we can replace this with a single
plane-list walk.
