c710f14cc5 core: Replace gtk_get_default_locale usage
Clutter has an API to get the text direction but used to depend
on gtk3's translation domain. In order to avoid broken i18n
in case gtk3 is not installed, move the transtalable string to
clutter itself.

a16df485db clutter: Reduce default clutter_max_render_time_constant_us to 1000
Now that dynamic max render time uses a new algorithm and takes dispatch
lateness into account, this seems worth a shot. We'll see how it works
out in the wild.

The net result compared to before these changes is still slightly higher
(by ~0.5 ms) minimum latency for me, as measured by
weston-presentation-shm. It should be less vulnerable to frame drops
though.

ca341ef1ea frame-clock: Simplify dynamic max render time calculation
Store only two values per kind of duration: The short term and long term
maximum.

The short term maximum is updated in each frame clock dispatch. The long
term maximum is updated at most once per second: If the short term
maximum is higher, the long term maximum is updated to match it.
Otherwise, a fraction of the delta between the two maxima is subtracted
from the long term maximum.

Compared to the previous algorithm:

* The calculcations are simpler.
* The calculated max render time has a slow exponential drop-off (by at
  most a few milliseconds every second) instead of potentially abruptly
  dropping after as few as 16 frames.

This should fix https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/4830
since the short term maximum should always include a sample from the
clock's second tick.

v2:
* Use divisor 2 instead of 4.

99850f4645 clutter/frame-clock: Use dispatch lateness for dynamic max render time
Dispatch lateness is the difference between when we wanted frame clock
dispatch to run and when it actually started running. This can be up to
1ms even under normal circumstances due to process scheduling
granularity, or even higher under load.

This keeps track of dispatch lateness of the last 16 frame clock
dispatches, and incorporates the maximum into the dynamic render time
estimate.

a897542876 clutter/actor: Stop transitions in children when removing
When we remove a child, we stop its transitions (animations), but we
didn't stop animations on grand children. What we did, however, was to
clear the stage views of the grand children, and this caused a bunch of
orphaned transitions (ClutterTimeline) and accompanied warnings.

Make it so that if we stop transitions, and clear stage views, also stop
transitions for the grand children. Detached children don't have a way
to continue animating anyway, since they have no stage view (thus frame
clock) to be driven by.

61cc31c3ce clutter/actor: Show on all stage-views when actors have no allocation
When a badly behaving ClutterActor implementation manages to invalidate
the allocation after the layout phase and before painting, we have no
idea where the actor should be painted without running the whole layout
machinery again.

For paint volumes in this case we pretend the actor covers the whole
stage and queue full-stage redraws. When updating stage-views, we're
also handling this case, but not in the most graceful way. Just like
with paint volumes, we should assume an actor without a valid allocation
is simply everywhere, so set priv->stage_views to all available stage
views in that case.

fe01e423a3 clutter/stage: Always queue events in _clutter_stage_queue_event()
We've been sending all events to clients immediately for quite some time
now, so this is only really impacting the Clutter scene graph, not
clients anymore.

That makes this behavior a somewhat unnecessary optimization (it was
useful at the time it was added, but it's not anymore), which will only
make our lives harder when we actually expect an event to be queued
(eg. in tests), so remove it.

edc226a04d clutter: Process device removing events immediately when they come in
Having the stage device list be responsible for delivering the
same events twice (first immediately to clients, then later to Clutter)
was expected to be tricky, a sneaky problem with it right now is the
following case:

While collecting events for a stage update cycle, we get three touch
events from the backend: TOUCH_BEGIN(seq=1) -> TOUCH_END(seq=1) ->
TOUCH_BEGIN(seq=1)

What we do right now when we see a TOUCH_BEGIN event is adding a device
to the stage right when it comes in from the backend. And when we see
a TOUCH_END, we remove the device from the stage not immediately but
only after it went through the queue.

In the case of the three events mentioned above, with the current
behavior, this will happen when they come in from the backend:

- TOUCH_BEGIN(seq=1): device gets added to the stage with seq 1, event
 gets queued
- TOUCH_END(seq=1): Nothing happens, event gets queued
- TOUCH_BEGIN(seq=1): we try to add device to the stage, but seq 1 is
 already there, event gets queued

Now when we go through the queue and see the TOUCH_END, the device with
seq 1 gets removed, but on the subsequent TOUCH_BEGIN, we won't add a
new device, so this event (and all events with seq=1 that are still in
the queue) is now ignored by Clutter because it has no device.

What we want to do here is to cut short once the TOUCH_END event comes
in: Process queued events immediately and make sure the device is
removed from the stage list before a new device can be added. Same goes
for any other events that will lead to devices getting removed.

Small note: Since this leads to clutter_stage_get_device_actor()
returning NULL, I was wondering why we never crash because of this:
Turns out _clutter_actor_handle_event() handles self = NULL just fine
without crashing...

675321a2e5 clutter/actor: Rename paint_volume_valid to has_paint_volume for clarity
Rename the paint_volume_valid flag to has_paint_volume in order to
better reflect what it's for.

The name "paint_volume_valid" implies that the paint volume can be
invalidated and thus sounds like it's involved with some kind of
caching. The flag that's actually involved with caching is
"needs_paint_volume_update", while "paint_volume_valid" is only meant to
store whether the actor has a paint volume to work with.

So rename paint_volume_valid to has_paint_volume to avoid confusion
about which flag is used for caching.

2541979f8e clutter/text: Replace cached paint volume with the one cached by actor
Since ClutterActor now properly caches its paint volume and ClutterText
tries hard to invalidate its own cached paint volume on every redraw
anyway (that's more often than ClutterActor invalidates its own paint
volume), we can simply rely on the caching of the paint volume done by
ClutterActor and invalidate that on every redraw.

So remove the private cached paint volume from ClutterText and all its
invalidation machinery.

714f01048e clutter: Demote the new clutter_stage_grab() precondition check
There do indeed seem to be places in our own code that trigger grabs on
actors before they are realized. It was not the intention to change the
practical preconditions for GNOME 43, so make it an even lower minimum
that every caller ought to match: That the actor is attached to the stage.

Further constraining of these preconditions will have to wait until
branching for new development.

e3df7b3384 clutter: Undo actor grabs along with ::unrealize
If an actor is being unrealized or otherwise unparented, it's a good
indication that its grabs are now stale and possibly harmful. Ensure
these are dropped when the actor is unparented.

This is now an unlikely event, since there is code to also dismiss
grabs when a visible grabbed actor goes unmapped. But that may be
prevented from happening, or the ordering of circumstances allow a
grab to be created and an actor destroyed without going unmapped
first. This grab dismission on unmap stays as it matches the UI-level
expectatives that an actor must be visible to be grabbed.

85ef0d1a46 compositor-view/native: Check that the actor covers the the view
If we have a window that match the size (i.e. will pass the "fits
framebuffer" low level check), that doesn't mean it matches the
position. For example, if we have two monitors 2K monitors, with two 2K
sized windows, one on monitor A, and one on monitor both monitor A and
B, overlapping both, if the latter window is above the former, it'll end
up bing scanned out on both if it ends up fitting all the other
requirements.

Fix this by checking that the paint box matches the stage view layout,
as that makes sure the actor we're painting isn't just partially on the
right view.

The source field was removed from ClutterEvent with commit

With crossing events it's not that easy though, as crossing events
explicitly have a source and related actor that doesn't have to be the
same actor as the device actor. Since we kept around the "related" field
there anyway, let's also introduce a "source" field in
ClutterCrossingEvent and return that actor when get_source() is called

550f09a5e7 clutter/stage-view: Defer and accumulate redraw-clip on scanout
When taking the scanout path we still want to clear the
redraw-clip from the stage-view in order to ensure we skip
frames in `handle_frame_clock_frame()` if no new redraw-clip
was recorded.
This was not done previously as the accumulated redraw-clip was
needed for the next repaint, likely under the assumption that
scheduling a scanout repeatedly would be computationally cost-free.
This assumption does not hold in a VRR world.

In order to archive both, an accumulated redraw-clip for the next
paint and frame-skipping during scanout, introduce new API to defer
and accumulate redraw-clips until the next repaint.

dispatch didn't result in any KMS update, e.g. because it was triggered

but might be possible even with a single stage view if the cursor isn't

550b66d4e6 clutter/actor: Handle repicks when actors become reactive
The notification list in the GNOME Shell calendar popup triggers some
interesting interactions when closing a notification:

- Close button is clicked
- The notification animates to be hidden
- The next notification ends up hovered as a result of the animation
- The notification being hovered sets its close button as non-transparent
  and reactive
- The pointer is now again over a close button

At this point the reactiveness change should trigger a repick, so that
the new notification's close button is picked, and future button presses
are directed to it, but we do not handle this situation.

To fix this, handle actors becoming reactive so that if the closest
reactive parent has a pointer, it will be repicked again just in case
the pointer is over the newly reactive actor.

3d94c7cc2d clutter/actor: Do clutter_actor_destroy_all_children without an iterator
`clutter_actor_iter_destroy` will try to match up the iterator's `age`
with that of the parent ("root") actor:

```
g_return_if_fail (ri->age == ri->root->priv->age);
```

In a simple actor graph that's completely reasonable but somewhere in the
more complex graph of gnome-shell the parent's `age` was skipping ahead
faster than that of the iterator. This could happen in theory if the
destroy indirectly leads to more children being destroyed than the
iterator has visited.

So there's no evidence of actual corruption, only the age check might
fail in a `clutter_actor_iter_destroy` loop because the age check itself
can't handle all possible valid scenarios.

Since our only mandate is to destroy all children, we can do that reliably
without an iterator and thus without assuming anything about the parent's
`age` counter.

6c17aa66c6 clutter: Remove device/sequence entry when TOUCH_END get filtered out
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.

cd0c47a25a clutter: Shuffle handling of IM reset on button presses
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.

cfdca246f2 clutter/stage: Repick when pointer actor goes unmapped
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).

c64803770e clutter: Bail out and warn on reentry into mapping/unmapping cycle
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.

4a865424cd clutter: Set event as current_event when going through event filters
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.

f820bb3506 clutter: Keep actors dirty if a redraw was queued up during paint()
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().

The ClutterGestureAction base code would correctly try to cancel a

other portions of the actor tree stole input away from the gesture actor),

possibly leaving stale point information if the gesture collected input

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
