It takes coordinates in stage coordinate space, and will result in
a screen cast stream consisting of that area, but scaled up by the scale
factor of the view that overlaps with the area and has the highest scale
factor.

Will be used by the stage to not paint the overlays. We skip all
overlays since overlays are only ever used for pointer cursors when the
hardware cursors cannot or should not be used.

Either onto a framebuffer, or into a CPU memory buffer. The latter will
use an former API and then copy the result to CPU memory. The former
allocates an offscreen framebuffer, sets up the relevant framebuffer
matrices and paints part of the stage defined by the passed rectangle.
This will be used by a RecordArea screen cast API. The former to paint
directly onto PipeWire handled dma-buf framebuffers, and the latter for
PipeWire handled shared memory buffers.

A paint flag affects a paint operation in ways defined by the flags.
Currently no flags are defined, so no semantical changes are defined
yet. Eventually a flag aiming to avoid painting of cursors is going to
be added, so that screen cast streams can decide whether to include a
cursor or not.

Try to bypass compositing if there is a fullscreen toplevel window with
a buffer compatible with the primary plane of the monitor it is
fullscreen on. Only non-mirrored is currently supported; as well as
fullscreened on a single monitor. It should be possible to extend with
more cases, but this starts small.
It does this by introducing a new MetaCompositor sub type
MetaCompositorNative specific to the native backend, which derives from
MetaCompositorServer, containing functionality only relevant for when
running on top of the native backend.

Make it possible to cause the next frame to scan out directly from the
passed CoglScannout. This makes it possible to completely bypass
compositing for the following frame.

Transitions are used for animating actors when e.g. going from/to
fullscreen, and the like. We need to know such things when deciding
whether to avoid compositing a window actor, so make add API visible to
mutter that checks whether there are any transitions active.

click_action_query_long_press() can potentially schedule more than
one timeout, since it doesn't clear any already-existing timeout.
Make sure to clear the long press timeout before scheduling a new
one.

Like the click action, it makes sense to cancel the ongoing gesture
when the action is disabled. Do so by overriding our new friend,
ClutterActorMeta.set_enabled, and canceling the gesture when disabling
the action.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1188
ClutterClickAction, like other actions, can potentially be disabled
at any time (that is not during painting). When that happens with
ClutterClickAction, it must release all timeouts and disconnect from
the stage's 'capture-event'.
Override ClutterActorMeta.set_enabled and release the click action
when the action is being disabled.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1188
Various subclasses of ClutterActorMeta need to reacto to being
disabled. Right now, however, the only way to do that is by
overriding GObject's 'notify' vfunc, and doing a string comparison
against "enabled".
Add a new vfunc to ClutterActorMeta in order to replace this bad
practice.

In the unlikely case we have multiple rectangles in our selection
(selection spanning several lines, or across LTR/RTL bounds), paint each
of those instead of setting a CoglPath-based clip/fill.

With the introduction of "shallow" relayouts, we are now able to enter
allocation cycles not only at the stage but also deeper down the
hierarchy if we know an actors allocation isn't affected by its children
since the NO_LAYOUT flag is set.
Now that means when queuing relayouts it's possible that
`priv->needs_allocation` gets set to TRUE for some actors down the
hierarchy, but not for actors higher up in the hierarchy. An actor tree
where that happens could look like that:
stage -> container -> container2 (NO_LAYOUT) -> textActor
With that tree, if the "textActor" queues a relayout, "container2" will
be added to the relayout hashtable of the stage and the actors "stage"
and "container" will have `priv->needs_allocation` set to FALSE.
Now if another relayout on the stage actor is queued,
`clutter_stage_queue_actor_relayout()` currently removes all the other
hashtable entries in favour of the stage entry, (wrongly) assuming that
will allocate everything. It doesn't allocate everything because in the
example above "container" has `priv->needs_allocation` set to FALSE,
which makes clutter_actor_allocate() return early before allocating its
children, so in the end "container2" will never get a new allocation.
To fix this, stop flushing the relayout hashtable when queuing a
stage-relayout and still add new entries to the hashtable if a stage
relayout is already queued to make sure we still go through all the
previously queued "shallow" relayouts. That shouldn't hurt performance,
too, because as soon as an actor got allocated once, it doesn't need an
allocation anymore and should bail out in clutter_actor_allocate() as
long as it's absolute position didn't change.

Disabling a click action after a button-press but before a
button-release is captured makes ClutterClickAction connect to
captured-event and never disconnect.
This change fixes it by making sure the captured-event is only
processed if the action is still enabled, otherwise releasing
the action (reset state) and propagating the event.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1170
Nothing should ever disable an actor modifier (e.g. effect) during the
paint sequence, nor should any actor be set or unset on it. If this
would happen, log warnings so that it can be tracked down.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1166
When selecting the pick regions for an actor we were not considering
whether the actor was allocated and that was causing issues where the
preferred width/height of the actor was used when deciding whether
the actor should be considered as a pick target.
Check if the actor has a valid allocation, in addition to being mapped
and being in pick mode, in clutter_actor_should_pick_paint().
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1169
The input method can assign a negative value to
clutter_input_method_delete_surrounding() to move the cursor to the left.
But Wayland protocol accepts positive values in delete_surrounding() and
GTK converts the values to the negative ones in
text_input_delete_surrounding_text_apply().
https://gitlab.gnome.org/GNOME/mutter/issues/539
Fix a regression that got introduced with
c483b52d24 where we started passing the
redraw_clip to paint_stage() instead of creating a temporary view_region
for unclipped redraws: In case we detect an invalid buffer age, we fall
back to doing an unclipped redraw after we passed the first check
setting up may_use_clipped_redraw. That means we didn't reset the
redraw_clip to the view_rect, and we're now going to redraw the stage
using the original redraw clip even though we're swapping the full
framebuffer without damage.
To fix that, check for the buffer age before setting up the
fb_clip_region and the redraw_clip and set may_use_clipped_redraw to
FALSE if the buffer age is invalid, too. This ensures the redraw_clip is
always going to be correctly set to the view rect when we want to force
a full redraw.

When calculating the resource scale of a clone source, we might end up
in situations where we fail to do so, even though we're in a paint. A
real world example when this may happen if this happens:
* A client creates a toplevel window
* A client creates a modal dialog for said toplevel window
* Said client commits a buffer to the modal before the toplevel
If GNOME Shell is in overview mode, the window group is hidden, and the
toplevel window actor is hidden. When the clone tries to paint, it fails
to calculate the resource scale, as the parent of the parent (window
group) is not currently mapped. It would have succeeded if only the
clone source was unmapped, as it deals with the unmapped actor painting
by setting intermediate state while painting, but this does not work
when the *parent* of the source is unmapped as well.
Fix this by inheriting the unmapped clone paint even when calculating
the resource scale.
This also adds a test case that mimics the sequence of events otherwise
triggered by a client. We can't add a Wayland client to test this, where
we actually crash is in the offscreen redirect effect used by the window
dimming feature in GNOME Shell.

This is so that cogl-trace.h can start using things from cogl-macros.h,
and so that it doesn't leak cogl-config.h into the world, while exposing
it to e.g. gnome-shell so that it can make use of it as well. There is
no practical reason why we shouldn't just include cogl-trace.h via
cogl.h as we do with everything else.

This adds a new frameclock tracing mark for a single cycle of the frame
clock. Doing so allows Sysprof to potentially do more with the information
that happens during the frameclock. For example, we can now find
allocations that happen while the frame clock is advancing.

offset_scale_and_clamp_region() creates a new region resulting in
view_damage which at this point is the only thing left pointing to what
originally was fb_damage getting overwritten and being leaked.

The stage window handled the redraw clip in a global manner; this would
interfere if we want to paint views individually as it'd mean
intersecting views (i.e. mirrored monitors) would loose the redraw clip
once the first view was painted. It also is awkward to have a global
state for something that is built up before redrawing, and only really
valid during paint, due to buffer damage history.
This commits removes all redraw clip management from the stage window,
moving it all into the stage views. When a redraw clip is added to the
stage, every affected view will get the same redraw clip added to it,
and eventually when painted, the stage window (ClutterStageCogl) will
retrieve the redraw clip for each view as it repaints them.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1042
Instead of users fetching it via `clutter_stage_get_redraw_clip()`, pass
it via the paint context. This is helpful as it is only valid during a
paint, making it more obvious that it needs to be handled differently
when there is no redraw clip (i.e. we're painting off-screen).
