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.

For better or worse, cursor planes can only be used by uploaded SHM
buffers right now, so ignore them when we're calculating the acceptable

It's invalid for a client to pass the compositor's supported version
directly to wl_registry_bind. For instance, under wlroots the client
will bind to wl_output version 4 and crash because it doesn't handle
the new "name" event.

Transforming the scanout damage by the zoom will result in rectangles
outside of the display, and some with negative co-ordinates. This makes
at least some drivers unhappy (tested on vmware), and the page flip fails,
and weston hangs indefinitely.

The invariant is clearly documented in code comments, but the code
failed to ensure it in all cases. Fix it.
There is one very specific protocol sequence triggered by a development
version of the Wine Wayland driver when Chrome (win64 app) is switched
from window to fullscreen and then back by pressing F11 key. The switch
back triggered
weston: ../libweston/color.c:217: weston_paint_node_ensure_color_transform: Assertion 'it->surf_xform_valid == false' failed
For some reason, that specific protocol sequence causes
weston_compositor_build_view_list() to create a transient second view
for a sub-surface. In the Chrome traces, I have seen that happen twice
per run. The first time it works, the old view gets immediately
destroyed. The second time (during un-fullscreening) a new transient
view is create and then it fails the invariant check.
The fix is in weston_paint_node_create() which is supposed to ensure the
invariant. However, it went through the (new) view's paint node list,
which will not contain paint nodes from other views. In hindsight this
is an obvious bug, but perhaps all views having exactly one associated
surface each somehow confused the author. Since the invariant is about
surface+output, go through the surface's paint node list instead. That
list contains all the relevant paint nodes by definition.

Commit 0e4f097d broke opaque regions, and since then weston will waste
time rendering occluded areas.
I think this is because we're taking the intersection of the opaque
and scissor regions even when the scissor region isn't enabled.
An easy test is to turn on triangle fan debugging with the gl renderer,
then run weston-simple-damage and move another opaque application such as
weston-terminal over it.

The code currently checked the return value of weston_config_section_get_bool()
which is incorrect. The return value of weston_config_section_get_bool() is
zero whether the config option is present or not, and it is non-zero in case
the config option is not present.
The code must check whether the config option is either true or false,
or in case the option is not present then default to false. Adjust the
code accordingly.

Since commit 992ee045f1 we create a new surface when we update the cursor
image. This broke animated cursors by discarding any existing frame
callback used for timing, and moving the setup for frame callbacks to
after the commit on the pointer surface.
To fix this we need another surface commit for the frame callbacks, but
this alone is not enough to fix the regression, as a lingering kludge
intended to fix problems when reusing the pointer surface is no longer
working as intended.
Since we no longer re-use the same surface, we can delete the old surface
on pointer exit, along with any callbacks set on it. Then a frame callback
will be recreated naturally. This lets us remove the now broken kludge
from the past and restore animated cursor functionality.

When EGL initialization fails (failure to create a GLES3 or GLES2
context) we will end up calling gbm_device_destroy() twice, once
in init_egl() and once in the drm_backend_create() error path.
Given that we should also take care of properly destroying the gbm
device when we don't have any inputs for instance, mark the gbm device
as NULL to avoid calling gbm_device_destroy() once more when destroying
the DRM-backend.

As mesa includes gbm_bo_get_fd_for_plane() from 21.1.0 version onwards,

Replaces potential corruption signal emit call sites with the more safer

Signed-off-by: Marius Vlad <marius.vlad@collabora.com>
This simulates an output removal which should trigger a crash when
the compositor is shutdown abruptly by having a view with a listener installed
on its output_destroy signal.
This patch assumes that weston_compositor_remove_output() has already
been amended to use the more safer version for triggering signal
emission.
As both shells use this construct it should catch any potential signal
corruption.
