Prior to 'compositor: Destroy actors when unmanaging', window actors
were destroyed when the compositor object was destroyed, long after the
windows were unmanaged, however, when this instead changed to happen
when unmanaging, with the original goal to avoid having these actors try
to interact with the disposed MetaCompositor instance, it caused an
issue where window actors would be indirectly destroyed as a side effect
of their parents being destroyed, which caused some fallout in the logic
handling window-close animation tracking, which relies on
meta_window_actor_queue_destroy() being called before a window actor is
actually destroyed.
Fix this by unmanaging windows before unmanaging the compositor.
From an X11 point of view, this should be harmless, since all it really
do is call XCompositeUnredirectSubwindows().
For the native backend and the common behavior, all unmanaging the
compositor instance does is destroy clutter actors, so doing so after
window actors were already cleaned up should not be a problem, as this
was the case before too.

Quoting Ray Strode:
we don't expose a way to explicitly save the session in gnome anymore
afaik, and I don't think it's going to show on log out because
I believe we use the FORCE flag from the log out dialog.

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.

'kms/impl-device/simple: Get the buffer handle from MetaDrmBuffer'
changed how fb ids are generated, but it only made it fully work with
atomic mode setting. For legacy/simple mode setting, it only handled the
primary plane buffer, not the hardware cursor.
Fix this by making sure the fb id is generated also in the legacy mode
setting case.

When an X11 window becomes an all-workspace window its `workspace` is
set to NULL before `meta_window_x11_current_workspace_changed()` is
called. The latter then checks for `workspace` being NULL (which also
happens when unmanaging) and then returns early. So this does not update
`_NET_WM_DESKTOP` to 0xFFFFFFFF. Instead it remains at the workspace the
window was on before. This was causing programs like `wmctrl` to switch
to this old workspace when activating such a window.
Fix this by checking if the window is unmanaging instead.

Simply signal preedit string changes from/to NULL once, in order
to avoid unwanted activity in the client side. We do still need to
send the preedit once each .done event, if there is one, in order
to behave according to the protocol when it matters the most.

With the unthrottled input emission, we ended up often getting the
cursor updates long before any damage had been posted, meaning that if
you moved around the mouse pointer where the mouse had a high enough
refresh rate, we'd effectively stall the screen cast stream by only
sending cursor updates and nothing else.
Fix this by scheduling an update when we get a cursor update, then
sending a cursor-only frame after any damage and relayout has been
processed, but only if there is no queued damage that will cause an
actual repaint.

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.

This handle is used by the legacy KMS API; lets avoid having to have GBM
specific code where this is done by letting the MetaDrmBuffer API, that
already has this information, expose it.

We'd put the message in a variable called `message`. If something passed
to meta_topic() was called `message`, it'd end up being `NULL` in the
log entry. Avoid this by making the local message variable a bit more
"on topic".

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 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.

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.

The clutter_text_delete_text() function used underneath expects character
offsets for both start/end position. Fix the end position passed an offset

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).

DMA buffers might be allocatable, but it doesn't mean the driver doesn't
fail when we try to allocate a buffer with an implicit modifier. Using
the proprietary NVIDIA driver for example, it will fail. Lets catch this
up front and avoid advertising DMA buffer support when we know it won't
work.

As of currently, we only emit .done() on actual changes coming from the
ClutterInputMethod/ClutterInputFocus. With the recent changes in the
interpretation of serials, it becomes more important now that the
compositor acknowledges every .commit done by the client, in order to
keep them feeding future IM state updates.

Compensate the protocol statelessness with our ClutterInputFocus
statefulness. This becomes more necessary now, since sending

MetaCursorRendererNative only updates the cursor state when the
underlying texture changes. The cursor scale and transform do not
trigger updates. This results in wrong cursor orientations on rotated
displays. Use both texture changes and scale and transformation changes
to figure out when to update the cursor state.

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.
