7d3ff66724 clutter/stage: Remove unused nullable annotation
This annotation wasn't taken into account because of the colon, but shouldn't
be applied as there is no way a NULL ClutterGrab can be returned.

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.

39ff8d15e2 wayland: Reset ClutterInputFocus on focus changes
Focus changes should trigger an IM reset, as some engines do want
to maybe commit the preedit string before changing focus. In addition,
we do not want the preedit string to be able to move between
windows/applications.

Ensure that the commit string is committed when the IM deems so, and
ensure we send a .done event disntinct to the .leave event, so that
the client doesn't miss the commit.

a9a890164a clutter: Actively update ClutterText surrounding text on changes
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.

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).

6e458f9462 clutter: Pass events to pointer a11y before going through filters
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.

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.

91ae72acdf core: Account ClutterStage grabs on Wayland key focus synchronization
When switching between the existence and not of a stage ClutterGrab, we
would correctly attempt to synchronize key focus from the perspective of
the Wayland clients.

But this synchronization should do its own checks about existing stage
grabs before determining a client window has key focus or not.

Add that check, so that grabs correctly unfocus the keyboard in Wayland
clients, in addition to pointers and touch.

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().

eb4307c350 x11: Set WM_S0 last
With Xwayland on demand, a number of maintenance X11 applications need
to be run first, before Xwayland starts accepting requests from the
normal clients, as soon as the WM_S0 selection is acquired by mutter.

On startup, mutter also sets a number of X11 properties that can be
queried by X11 clients.

Unfortunately, mutter acquires the WM_S0 selection before setting those
properties, so mutter and the first regular X11 client will race on
startup.

As a result, the X11 properties set by mutter on startup may not be
available to the very first X11 client when Xwayland starts.

To avoid that issue, make sure to take the WM_S0 selection last when
opening the display.

de8927e075 xwayland: Init DnD on every Xwayland start
Currently, meta_xwayland_shutdown_dnd() is called from the handler
on_x11_display_closing() triggered from the signal "x11-display-closing"
hooked up from meta_xwayland_init_display().

Once the signal has been triggered, on_x11_display_closing() removes the
signal handler, disconnecting from the signal.

As meta_xwayland_init_display() is called from meta_display_new() which
is issued only once, the signal handler is not restored again.

As a result, meta_xwayland_shutdown_dnd() is not called anymore after
Xwayland has been restarted, but meta_xwayland_init_dnd() will check and
assert that the manager's DND object is NULL.

Basically, restarting Xwayland more that once will trigger an assertion
failure in mutter. That's even more of a problem with autoclose-xwayland
where Xwayland is expected to terminate when there is no meaningful X11
client remaining, which can happen multiple times during the lifetime
of a user session.

To make sure that meta_xwayland_init_display() is called for every new
instance of Xwayland, simply keep the signal hooked in place by not
disconnecting it when triggered.

This reverts commit 9a10b8ff94.

Even though, originally, this issue was first introduced with commit
b4fe1fdd95 ("xwayland: Make setup/teardown
a bit more symmetrical") which didn't actually kept 'x11-display-setup'
and 'x11-display-closing' connected.

8354289650 onscreen/native: Fall back if COPY_MODE_SECONDARY_GPU fails to init
This can happen if we've got a GBM driver that is incomplete or
buggy for any reason. Currently this includes the Nvidia driver
when used as a secondary GPU, and as soon as they fix that it will
use the fast path instead.

Falling back means we can still use it as a KMS device with all rendering
done on the primary GPU instead. Just like a DisplayLink.

It's slow, but at least the screens all light up now and you get a
usable desktop. Surprisingly it's still a better experience than using
Xorg, maybe because we can flip the outputs independently with the
native backend.

  non-touchpads.
- Devices that are both a tablet and a touchscreen prefer the tablet
  relocatable schema. This works for both aspects as the touchscreen

1fda60f03e clutter: Add compatibility code to get input capabilities from device type

In the mean time, keep these working on top of a ClutterInputDeviceType,
but transform that into capabilities on device construction so users can
rely on the new flagset.
