Clutter is a "scope", so everything under should be its own
"sub-prefix", e.g. changes to ClutterActor should be prefixed
'clutter/actor', ClutterFrameClock with 'clutter/frame-clock',
CoglFramebuffer with 'cogl/framebuffer' etc.

So that it can merge things with an even more locked down master branch.
It's given the name "Marge Bot", and the E-mail

It'd happen that the test runner would get CPU starved, and not see the
frame-clock changed notification before the timeline stopped. Decrease
the risk for this by moving the initial position of the actor having its
position transitioned to be closer to the view edge. This means the
frame clock will be changed earlier, increasing the chance of the
timeline not stopping before the relayout happens.

For X11 grabs, the pattern matching mechanism would simply ignore
applications which have neither WM_CLASS nor WM_NAME set.
When dealing with an override redirect window however, it is not
uncommon that these window have neither value set as these window are
supposed to be ignored by the window manager.
When the WM_CLASS or the WM_NAME is not set by the client, assume the
value is empty so the pattern matching can allow for these.

Monitor tile info is possible to fetch when RANDR version 15 is exposed
by the X11 server. We had inverted the check meaning that only if older
versions were advertised would we attempt to init the tile information.
Fix this guard, thus fix monitor tiling on X11.

As explained in https://gitlab.gnome.org/GNOME/mutter/-/issues/1494,
with commit 29caa5bea5 we stopped queueing
a relayout for the parent of the removed actor in
clutter_actor_remove_child_internal(). This relayout was, as opposed to
the relayout in clutter_actor_real_hide()/clutter_actor_real_unmap(),
queued unconditionally without looking at the parents NO_LAYOUT flag.
Now while that relayout in clutter_actor_remove_child_internal() would
do unnecessary work if the parent had the NO_LAYOUT flag set, it did
also queue a redraw of the parent, which is necessary in any case.
So by removing that relayout in clutter_actor_remove_child_internal(),
we stopped queueing redraws for NO_LAYOUT parents when a child gets
removed from the scenegraph. This caused bugs where the texture of the
child would be left visible on the screen even though the child got
destroyed.
To fix this, make sure again that we always queue a redraw on the parent
when unmapping a child.

Not calling libinput dispatch in the backend constructor defeats the
logic in post init as the device added events have not been processed
yet.
So instead of trying to guess the cursor initial visibility, simply
update it along when devices get added.
Additional benefit, we do not need to walk the all device list looking
for touchscreens anymore, we just need to check the device being added
since the current logic is to hide the cursor as soon as a touchscreen
is found.

At startup, libinput dispatch is called from the MetaSeatNative
constructed callback.
That means that we may get libinput events even before the default seat
is set.
In turn, processing those events may trigger the use the default seat
while it's still not set yet, and cause a crash of gnome-shell/mutter
at startup.
A simple reproducer for this is to start gnome-shell/mutter with a
tablet connected and the stylus in proximity, the proximity event will
cause gnome-shell/mutter to crash at startup.
To avoid that issue, avoid dispatching libinput events early from the
MetaSeatNative constructed callback, those events will eventually get
processed when the seat and the backend are all setup.

Commit 8bdd2aa7 would offset the window position by the difference
between the configured window size and the committed size from the
client to prevent the window from drifting while resizing.
This, however, did not take into account the actual geometry scale, so
when using any scale greater than 1, the window would rapidly drift away
due to that offset.
In order to solve this, we need to make sure we store away the pending
window configuration in the stage coordinate space, in order to not
loose precision. When we then calculate the offset given the result from
the client, it'll use the right scalars, while before, one scalar was in
surface coordinates, while the other in stage coordinates.

We're just a "ninja coverage" away from getting the full report,
it is not that much extra to the pipeline. Also, fix bugs that
accumulated since the manual task was added, e.g. let the full
built+tested tree available on the coverity stage.

We want the bounding box so `ceilf` seems more appropriate. It was
only written using `roundf` before as a workaround for inaccuracies
coming out of `clutter_actor_get_transformed_size` that would have
tricked `ceilf` into landing on the wrong integer. But that's since
been fixed by 67cc60cbda so we can use `ceilf` now.

The redraw_pending boolean is used to schedule the first stage update
after starting Clutter. This flag is superfluous because we have the
pending_finish_queue_redraws flag which does the same.
While at it, also remove the redraw_count debug variable, since there
should be better ways to count the number of queued redraws nowadays,
for example Sysprof marks.

Queueing a redraw with a clip is easy enough and this function is
private anyway, so remove it and call _clutter_actor_queue_redraw_full()
instead in the one function using it.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1527
ClutterRedrawFlags are a way to give Clutter additional context
about what it needs to redraw. There currently is only one flag defined,
CLUTTER_REDRAW_CLIPPED_TO_ALLOCATION, this flag would clip the redraw to
the actors current allocation.
Since ClutterActor also provides the clip_to_allocation property (which
affects the paint volume of the actor instead of only one redraw), the
additional CLIPPED_TO_ALLOCATION flag seems unnecessary. It's also only
defined to be used privately in Clutter, which it never is, so let's
remove it.

Turns out the g_signal_has_handler_pending() call in
update_stage_views() is actually more expensive than comparing the
sorted list (which is usually very short), so remove that and simply
always emit the signal.

This commit introduces a few important changes in order to
acommodate graphene_ray_t. Most of them are positive changes,
so don't panic :)
The first very visible change is that neither the actor box
nor the clip rectangles are projected before being pushed.
This required changing the parameters of the related functions
at both ClutterPickContext, and ClutterPickStack, to receive
boxes instead of vertices. These rectangles are projected on
demand now, so in the best case (first actor picked) only
one projection happens; and in the worst case, it projects
as much as it does now.
The second important change is that there are no more checks
for axis-alignment anymore. That's because picking now happens
in 3D space, using triangles.
Talking about triangles in 3D space, this is what is used now
for picking. We break down each actor rectangle in 2 triangles,
and check if the projected pick point is inside any one of them,
of if the ray intersects any one of them. The same check happens
for the clip rectangles.
Checking the projected pick point is both an optimization for the
2D case, and a workaround to graphene_ray_t problems with float
precision, which is specially visible on edges such as the top
bar.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1509
ClutterPickStack is a new boxed type that stores the vertices
and clip rectangles. It is meant to be a byproduct of picking,
and takes over most of what ClutterStage currently does.
It introduces a 'seal' system, inspired by MetaKmsUpdate. After
the pick operation is done, and the rectangles are collected,
the pick stack is sealed, and is not allowed to be externally
modified anymore. Internally, it still can invalidate pick
records when an actor is destroyed.
For now, it handles both the clip rectangles, and the matrix
stack, separatedly. Future commits will rearrange this.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1509
Because clones may not have identical geometry to their source actors.
So we can't use the geometry of the source actor to decide to take the
more optimized (more clipped) path.
