If we returned early in one of the checks but already assigned the
surface role, we'd later run into a double-free and crash. Just do
the checks at the beginning.
Also add a missing return statement that was left out in commit
88ff196fe3 and tighten the parent surface check.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1415
The spec allows `parent_resource` to be `NULL`, requiring the parent
surface to get specified by some other protocol. Send a protocol error
with some meaningful explanation instead of crashing.

Currently, the maximum size for a mouse pointer bitmap for screen
casting is 64x64 pixels.
However, this limit is hit way too often as it is way too low and
results in crashes in either gnome-remote-desktop or mutter.
For example: The a11y settings in g-c-c allow setting a larger pointer
bitmap in order to increase the visibility of the mouse pointer.
With the current limit of 64x64 pixels it is not possible to use the
larger variants of the default mouse pointer bitmap, without
experiencing any crash.
Another way to hit the limit is when display scaling is used or some
game uses a custom (large) mouse pointer bitmap.
The VNC backend in gnome-remote-desktop does not seem to have a maximum
pointer bitmap size.
The RDP backend on the other hand has a maximum pointer bitmap size at
384x384.
Use this size (384x384) as maximum size instead of the current 64x64
size for mouse pointer bitmaps to avoid crashes in mutter and
gnome-remote-desktop and to ensure that bigger mouse pointer bitmaps
can be used.

It is linear config manager created when ensuring configuration.
However, the switch config is not set as LINEAR, but left as UNKNOWN.
This leads switch mode OSD always shows "Join Displays" icon, rather
than the next icon which is "External Only" after connect an external
display and press Super+P once at first time since mutter starts.
This patch moves switch config setting into
meta_monitor_config_manager_create_linear() (and the sibling functions)
to well prepare the monitors config and avoid missing settings.
This is a regression introduced by 149e4d6934.
Fixes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1362
Clients can set minimum and maximum to identical values to indicate a
fixed-size window. A compositor can ignore these requests and thus a client
has to ensure these limits.
To support clients that do not ensure these size limits by themselves and
to skip unnecessary function calls, we will prevent resizing requests by
the client if a fixed-size has been requested.
https://gitlab.gnome.org/GNOME/mutter/-/issues/1331
We're moving towards not supporting stand-alone application style
clutter stages, meaning the stage tests use will be reused instead of
recreated. To make this feasable, tests must clean up after themself.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1364
meta_run() is still left intact and does the same as before; the new
functions are only intended to be used by tests, as they may need to set
things up after starting up. Doing so linearly in the test case is much
easier than adding callbacks, so meta_run() is split up to make this
possible.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1364
The delete event was used for signalling the close button was clicked on
clutter windows. Being a compositor we should never see these, unless
we're running nested. Remove the plumbing of the DELETE event and just
directly call meta_quit() when we see it, if we're running nested.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1364
We checked if we were using the usig the X11 backend to decide when to
deal with a11y event posting - in order to make the clutter code less
windowing system dependent, make this check a check whether we're a
display server or not, in contrast to a window/compositing manager
client. This is made into a vfunc ot ClutterBackendClass, implemented by
MetaClutterBackendNative and MetaClutterBackendX11.

Test that if a timeline got its frame clock from a parent of the
associated actor, if that actor moves across the stage so that the stage
views changes and thus the would be picked frame clock too, this is
noticed by the timeline so that it also changes to the correct frame
clock.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1404
Timelines where the frame clock was picked from a parent of the
associated actor didn't get notified about any stage views changes, as
it only listened on the associated actor. If that actor didn't actually
get its stage views changed (because it went from empty to empty), we'd
end up with a stale frame clock, leading to crashes.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1404
Flip flop resize, which is the result of respecting ConfigureNotify
makes test annoyingly racy, as one cannot do
clutter_actor_set_size (stage, 1024, 768);
wait_for_paint (stage);
g_assert_assert (clutter_actor_get_width (stage) == 1024);
The reason for this is any lingering ConfigureNotify event that might
arrive in an inconvenient time in response to some earlier resize.
In order to not risk breaking any current behavior in the X11 CM case
(running as a compositing window manager), only avoid changing the stage
size in response to ConfigureNotify when running nested.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1404
This aims to make sure a view and its resources are destroyed when it
should. Using references might keep certain components (e.g frame clock)
alive for too long.
We currently don't take any long lived references to the stage view
anywhere, so this doesn't matter in practice, but this may change, and
will be used by a to be added test case.

Just as wl_shm, hook up the Wayland DMA-BUF protocol to the 64 bit half
point pixel formats too. This makes it possible for Wayland EGL clients
to use 64 bit pixel EGL configurations.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/804
Now that cogl understands them, hook wl_shm up so they can be used.
This also bumps the wayland-server version dependency to 1.17.90, which
corresponds to the master branch of wayland. The new formats will be
available in 1.18.0.

Without doing this, we'd use the same sprite that was last set by
mutter, most likely a leftptr cursor, and fail to update when e.g.
moving the pointer above a text entry and the displayed cursor updated
to a cursor position marker.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1391
The displayed cursor is the one displayed on the screen, e.g. via the
hardware cursor plane, by Xorg, or using the stage overlay.
When screen recording under X11, we don't get a stream of pointer and
cursor updates, as they might be grabbed by some other client. Because
of this, the cursor tracker or cursor renderer are not kept up to date
with positional and cursor state.
To be able to use the stage overlays when recording, we need to be able
to update the overlay without updating the displayed cursor, as we
shouldn't update the X server with cursor state we just retrieved from
it.
Thus, to achieve this, create a separate overlay cursor pointer. When
being a display server, they are always the same, but when using X11,
during screen recording, the overlay one will be polled at a fixed
interval to get a somewhat up to date state.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1391
Always force-track the cursor position (so that the X11 backend can keep
it up to date), and if the cursor wasn't part of the sampled
framebuffer when reading pixels into CPU memory, draw it in an extra
pass using cairo after the fact. The cairo based cursor painting only
happens on the X11 backend, as we otherwise inhibit the hw cursor.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1391
On X11 we won't always receive cursor positions, as some other client
might have grabbed the pointer (e.g. for implementing a popup menu). To
make screen casting show a somewhat correct cursor position, we need to
actively poll the X server about the current cursor position.
We only really want to do this when screen casting or taking a
screenshot, so add an API that forces the cursor tracker to track the
cursor position.
On the native backend this is a no-op as we by default always track the
cursor position anyway.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1391
Only when the cursor isn't handled by the backend is the overlay made
visible. This is intended to be used when painting the stage to an
offscreen using clutter_stage_paint_to_(frame)buffer() in a way where
the cursor is always included.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1391
Detect displays marked as 'non-desktop' by the kernel and skip them when
creating the outputs. Mutter is not able to render images that are shown
properly on those devices anyway.
This avoids lighting up attached VR HMDs and showing the GDM login
screen between the eyes in a VR HMD instead of on the monitor.
