ClutterColorState, that is a GObject. each ClutterActor would own
such an object, and it'd be set via a GObject property.
It would have an API to get the colorspace, whether the actor
content is in pq or not, and things like that.
if it is NULL, it will default to color state with sRGB colorspace.

There are no 'features' left, the last one, GLSL shader support, was
moved to Cogl.
This also move the Cogl context creation to a more sensible place, as it
was hidden away in the feature initialization.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2015>
The Cogl feature was removed a while back, while Clutter just hard coded
it to TRUE. Lets remove the confusion that GLSL isn't supported and just
remove the (dead) fallback paths.

A slightly annoying "feature" of Clutters debug messages is that it also
logs the filename and line of the current debug message. If you don't
have an ultrawide monitor, this can be very annoying and cause lots of
linebreaks in the debug logs.
So remove that debugging feature and no longer log the filename and
line number with debugging messages.

This is a signal that will be emitted between the 'before-update' and
'before-paint'. It can be used to handle things when you know whether
there is an update, and you know whether a paint or not will happen, by
looking at the current damage.

Mutters event filter can prevent events from getting processed by
Clutter, this can also happen for TOUCH_END/CANCEL events. Processing
these events in Clutter is crucial for proper tracking of touch
sequences though, that's because Clutter adds a PointerDeviceEntry to
the stage on a TOUCH_BEGIN *before* going through the event filter, but
removes that entry on a TOUCH_END *after* going through the filter. So
Clutter really needs to see those TOUCH_END events, or else there will
be a stale PointerDeviceEntry on the ClutterStage.
Make sure those TOUCH_END/CANCEL events always get seen by Clutter by
removing the device entry immediately when those get filtered out.
Because there might still be events belonging to this sequence in the
event queue of the stage, we need to flush the queue before removing the
entry, too.

Unfortunately we cannot do this generically since the target of the
button/touch press does matter, e.g. tapping on the OSK, or clicking
the IBus candidates window. These situations should not trigger a
reset.
So be more selective about the situations where button/touch presses
trigger an IM reset, in the case of ClutterText these are still clicks
inside the actor, for Wayland's text-input it is when clicking the
surface that has text_input focus.
For all other situations where clicking anywhere else might make
sense to trigger an IM reset are covered by the focus changing paths,
that also ensure a reset before changing focus between surfaces/actors.

Focus changes should trigger an IM reset, as some engines do want
to maybe commit the preedit buffer before changing focus. Since
the preedit string is also cleared on reset(), we can do without
that explicit call.

Right now we have a bit of a mixed bag between an active model where
input foci set the surrounding text without being asked for (e.g.
wayland's text_input), and a passive model where the IM engines ask
for content.
Make ClutterText take the same side than text_input, so that dealing
with those is at least consistent.

I've overseen quite an important case in commit
98a5cb37d9: Repicking only when actors get
destroyed is not enough, we actually need to repick when actors go
hidden/unmapped.
While we could also listen to notify::mapped just like we listen to
notify::reactive, it seems better to avoid using property notifications
here due to the usage of g_object_freeze/thaw_notify() in ClutterActor.
It can lead to the stage receiving a notify::mapped with mapped = true
for a pointer actor, which really shouldn't happen (just like
notify::reactive with reactive = true shouldn't happen).

We want all pointer events to be passed through the pointer a11y
processing before going through event filters: Once we go through event
filters, events might be dispatched to Wayland and get filtered out.
With the changes to immediately dispatch events to wayland, this changed
and the pointer a11y is now no longer seeing any events going to wayland
clients. Fix it by shuffling things around a bit and letting pointer
a11y take a peek at events earlier.

There's a bunch of crashes right now where the assertions in
clutter_actor_set_mapped() after calling the map/unmap() vfuncs are
failing. The only way this can happen is by re-entering
clutter_actor_set_mapped() during the map/unmap recursion.
The reason for those crashes is that the shell hides/shows some actors
in response to crossing events and key-focus changes. These in turn get
triggered by the newly introduced ungrabbing of ClutterGrabs when an
actor gets unmapped, which triggers GRAB_NOTIFY crossing events and
key-focus changes.
Since these situations are hardly avoidable (it's a valid use-case to
hide/show something in response to a crossing/key-focus event), catch
the set_mapped() call early while we reenter the mapping machinery and
log a warning instead of crashing.

With the introduction of untrottled event delivery to wayland clients,
we moved the _clutter_event_process_filters() call outside of
_clutter_process_event(). This also moved the processing of event
filters outside of the timespan where the event is added to Clutters
current_event stack, making Clutter.get_current_event() no longer
available to anything happening inside mutters event filter.
One thing that happens in mutters event filter is detecting and
triggering keybindings like the alt-tab switcher. Now the alt-tab
switcher has a special case where it finishes and activates a window
right when the keybinding gets activated, relying on the current event
time as the timestamp to activate the window.
Now since the current event time is no longer available from inside
mutters event filter, we'd pass 0 to meta_window_activate(), causing
mutter to send a notification instead of actually activating the window.
To fix this, also set a current_event for the ClutterContext when going
through event filters, this makes sure Clutter.get_current_event_time()
works when called inside keybinding handlers.

In the right combination of circumstances, and given 2 actors (parent
actor P with an offscreen effect and child actor C), we may have the
following situation happening:
- A redraw is queued on the actor C, actors C and P are marked as
priv->is_dirty and priv->propagated_one_redraw.
- During paint() handling we paint actor P, priv->propagated_one_redraw
is turned off.
- We recurse into child actor C, priv->propagated_one_redraw is turned
off.
- A new redraw is queued on actor C, actors C and P are marked as
priv->is_dirty and priv->propagated_one_redraw.
- The paint() method recurses back, actors C and P get priv->is_dirty
disabled, priv->propagated_one_redraw remains set.
- At this point queueing up more redraws on actor C will not propagate
up, because actor C has priv->propagated_one_redraw set, but the
parent actor P has priv->is_dirty unset, so the offscreen effect will
not get CLUTTER_EFFECT_PAINT_ACTOR_DIRTY and will avoid repainting
actor C.
The end result is that actor C does not redraw again, despite requesting
redraws. This situation eventually resolves itself through e.g. relayouts
on actor P, but may take some time to happen.
In order to fix this, consider actors that did get a further redraw
request still dirty after paint().

Simplify the function arguments (the origin is just the actor that
the function is originally called from), and make it also handle
marking as dirty the actor that got the redraw queued up explicitly.

The ClutterGestureAction base code would correctly try to cancel a
gesture if it would receive GRAB_NOTIFY leave events (that would indicate
other portions of the actor tree stole input away from the gesture actor),
but it would mistakenly do so only if the gesture was already initiated,
possibly leaving stale point information if the gesture collected input
but didn't initiate yet.
This could be indirectly seen clicking with the mouse on OSK keys with
no motions in between, clicks would accumulate on the swipeTracker
gestures until the trigger point, so the third click could drag the
workspaces.
We do always want to unregister the related device/sequence here, do that
while still cancelling any already initiated gesture.

It does not make sense that the event "source" (aka the target) is
both content and recipient of a message. Not doing so, events become
largely independent of the actor that is receiving/handling an
event. This is small step toward making events opaque and immutable.
Every user of these API calls in our code have ported away from
them, but other users may remain in extensions, so make these
functions work on top of the alternative API without accessing the
soon to be removed event field.

This is just "necessary" for --nested stages, since the pointer is
allowed to leave the stage in that case. Since the only side effect
is that there is still a pointer focus somewhere inside the stage,
simply drop this.
This is a small leftover of commit b8f92a6ce4, since we stopped
handling the double ENTER event there.
