Mutter still relies heavily on singletons such as its MetaBackend.
For that, the backend implementation has a meta_init_backend() function
which is called at startup from meta_init(), which creates the desired
backend and sets the singleton which is returned by meta_get_backend().
Unfortunately, that means that the backend is never actually freed, and
all the code from the backend finalize function never actually get
called.
Add a meta_release_backend() to free the backend singleton.

The input settings constructor installs callback functions on device
added/remove and tool-changed.
However, on dispose, those signals are not disconnected, meaning that on
teardown, once the devices get removed eventually, the callback will
still fire and call the callback with freed data, causing a crash.
Make sure we clear the signals on devices on dispose, to avoid the crash
on teardown.

A boring one, with the exception that row and column needed to be
swapped. For the sake of consistency, the variable names were also
synchronized with the values they hold, so e.g. xy → yx, etc.

CoglMatrix already is a typedef to graphene_matrix_t. This commit
simply drops the CoglMatrix type, and align parameters. There is
no functional change here, it's simply a find-and-replace commit.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1439
Ideally, we would use Graphene to do that, however as of now Graphene
lacks these APIs so we still need these helpers. Since we're preparing
to get rid of CoglMatrix, move them to a separate file, and rename them
with the 'cogl_graphene' prefix.
Since I'm already touching the world with this change, I'm also renaming
cogl_matrix_transform_point() to cogl_graphene_matrix_project_point(),
as per XXX comment, to make it consistent with the transform/projection
semantics in place.

During seat initialization, we process early libinput events (adding all known
devices) before the seat gets a stage assigned. This causes warnings when trying
to handle the corresponding CLUTTER_DEVICE_ADDED events, as they are sent
stageless.
As it is definitely too soon to have those events sent meaningfully, filter
those events out and instead handle the CLUTTER_DEVICE_ADDED emission for all
known devices after the seat receives an stage. This makes the events guaranteed
to be emitted early in initialization, but not so soon that they can't be
handled yet.

Mutter itself is versioned now, so passing the version information
to the plugin is redunant now: The version is already determined by
linking to a particular API version (gnome-shell) or by installing
to a versioned plugin path (external plugins).

A Meta.WaylandClient() object has a GSubprocessLauncher object
passed externally. Currently this object is kept while the
WaylandClient object exists, but is is only needed until the call
to spawn is made.
This patch frees that GSubprocessLauncher just after that call,
thus freeing those resources.
Fix https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1462
This reverts the commits 372d73e275 and 1d20045247 - the special
case for alpha-less textures could only happen on Wayland, but now
the opaque region is also set in those cases.
This commit saves us some allocations, simplifies the logic a bit and
makes sure culling uses the same opaque region as our painting paths.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1463
Wayland clients using buffers without alpha channel are not expected to
set an opaque region. However, we rely on the opaque region for the fast
painting path in `MetaShapedTexture`.
Thus, make sure to always set an opaque region internally in those cases.
For X11 clients, wo do so already.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1463
Just like we used to before 30809665d8.
Because in some cases `clip_region` is able to shave off an extra pixel
from the edge of the redraw rectangle(s). And not shaving that off was
making the background rendering inconsistent with shaped-texture, causing
occasional off-by-one artefacts. Now both shaped-texture and
background-content agree on the clip region again that doesn't happen.

This is essentially a revert of
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/326. This commit
had the unintended side effect that the built sources are actually
rebuilt for every individual user of libmutter_dep. With there being more
tests and generated files, the number of targets to build is increasing
squarely.
Not doing this reduces the number of targets from 2044 to 874, thus
saving man hours and CI burnt cycles in the long run. There's the slight
risk of reintroducing the random build breaks, but mutter is essentially
doing as suggested at https://github.com/mesonbuild/meson/issues/1084
(the only difference being addressed in the previous commit), so meson
ought to behave as expected.

We only update the last device from actual input interaction here,
avoid this pair of events. This is specially nasty with
CLUTTER_DEVICE_REMOVED, since the device we're notifying upon will be
disposed soon after emission.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1460
Like it's done for the pointer in other places. Without a stage assigned,
some bits (like IM handling) may end up with events ignored, and misbehave.
Fixes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1413
The Meta.WaylandClient constructor receives a GSubprocessLauncher
as a parameter, and stores it internally. Unfortunately, its
refcount value isn't increased, which results in the object being
released twice.
This patch fixes this bug.
Fix https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1454
When a MetaBarrier is first created it allocates a backend
impl object which does the actual heavy lifting.
Unfortunately, that backend object is never freed.
This commit ensures the implementation gets freed when
the barrier object is freed.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1451
meta_barrier_destroy is responsible for removing the extra
reference added in meta_barrier_constructed.
Unfortunately, it fails to do this because of a misplaced early
return statement.
This commit removes the spurious return.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1449
This is already taken care of in meta_backend_monitors_changed(), called
from the same code paths that emit ::monitors-changed-internal. It is
better to leave this up to backend internals.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1448
We only did this if we weren't currently doing an interactive resize,
but since the finish_move_resize() is not the actual interactive resize
but the acknowledgment of the configure event that was emitted as a
result, we shouldn't limit ourself to the same flags used during resize.
This fixes temporarly "stuck" position of attached modal dialogs while
they are being resized.

In X, buttons 1, 2, 3 are left, middle, right. In evdev, the order is
BTN_LEFT, BTN_RIGHT, BTN_MIDDLE. So setting a scroll button to 2 gave us a
middle button in the X session and a right button in a wayland session.
Fix that by hard-coding the LMR buttons handling.

Even when a direct client buffer has a compatible format, stride and
modifier for direct scanout, drmModePageFlip() may still fail sometimes.
From testing, it has been observed that it may seemingly randomly fail
with ENOSPC, where all subsequent attempts later on the same CRTC
failing with EBUSY.
Handle this by falling back to flipping after having composited a full
frame again.
