Users of Clutter grabs may listen for notify::revoked changes in
order to know that their grab is no longer in charge of event
propagation, without the use of crossing events.
Since a ClutterGrab may stay in the stack and regain effects,
this notification also happens the other way around.

The MetaWaylandPointer used to put this together through
MetaCursorTracker cursor visibility, and ClutterSeat-level
inhibition API, applying the pointer focus changes due to
visibility logically to Wayland clients.
In order to make this work over all Clutter widgetry
instead of just Wayland clients, make the ClutterSeat-level
inhibition API control this feature at the ClutterStage picking
level, and leave/enter the seat pointer as appropriate.
By default, the seat pointer has (un)focus inhibited. The
MetaCursorTracker has been made another player in unfocus
inhibition, simply asking for the pointer to get its focus
while the cursor is visible.
This in practice means that picking code may return a NULL
actor, some asserts and preconditions had to be changed to
handle this, plus some test code slightly.

Transfer none was achieved using a stack GArray in the stage which
would get resized to 0 at the end of every frame to "free" it.
In the case of direct scanout however, painting the next frame only
happens after leaving fullscreen again. Until then the array just kept
growing and because GArrays don't reallocate when shrunk, this memory
remained allocated even after leaving fullscreen.
There is no cache benefit from storing paint volumes this way, because
nothing accesses them after their immediate use in the calling code.
Also the reduced overhead from avoiding malloc calls seems negligible as
according to heaptrack this only makes up about 2-3% of the temporary
allocations.
Changing this to transfer full and removing the stack array simplifies
the code and fixes the "leak".

This is a step in cleaning up the Clutter context management. By making
it a GObject it's easier to add e.g. properties and features that helps
with introspection.
For now, this means the context creation is changed to go via a
"constructor" (clutter_create_context()). This is so that the global
context singleton can be mantained outsid of ClutterContext, until it
can be removed.

The intention for ClutterContext is to be more or less the MetaContext
or CoglContext equivalent. Lets rename the type so that it becomes more
consistent with the other similar types.

In profilers with a timeline or flame graph views it is a very common
scenario that a span name must be displayed in an area too short to fit
it. In this case, profilers may implement automatic shortening to show
the most important part of the span name in the available area. This
makes it easier to tell what's going on without having to zoom all the
way in.
The current trace span names in Mutter don't really follow any system
and cannot really be shortened automatically.
The Tracy profiler shortens with C++ in mind. Consider an example C++
name:
SomeNamespace::SomeClass::some_method(args)
The method name is the most important part, and the arguments with the
class name will be cut if necessary in the order of importance.
This logic makes sence for other languages too, like Rust. I can see it
being implemented in other profilers like Sysprof, since it's generally
useful.
Hence, this commit adjusts our trace names to look like C++ and arrange
the parts of the name in the respective order of importance.

We don't actually need the host to be a container, so simply work on

This'll simplify dropping ClutterContainer entirely later, and
StViewport/ShellWindowPreviewLayout will also need to be updated for the

- Make Texture a parent GObject class and move the vtable funcs as vfuncs
instead of an interface as we would like to have dispose free the TextureLoader.
- Make the various texture sub-types inherit from it.
- Make all the sub-types constructors return a CoglTexture instead of their respective
specific type. As most of the times, the used functions accept a CoglTexture,
like all the GTK widgets constructors returning GtkWidget.
- Fix up the basics of gi-docgen for all these types.
- Remove CoglPrimitiveTexture as it is useless: It is just a texture underhood.
- Remove CoglMetaTexture: for the exact same reason as above.
- Switch various memory management functions to use g_ variant instead of the cogl_ one
Note we would still want to get rid of the _cogl_texture_init which is something
for the next commit

This used to be the HW device that triggered the crossing (i.e.
the mouse moving the pointer, etc), or the logical device if the
crossing event happened through other means than input device
events, e.g. relayouts.
The move to ClutterEvent constructors went a bit too far in
the simplifications and broke these expectations for input-generated
crossing events.
Make this event constructor behave like the other events: receive
a source device, and figure out the corresponding logical device from
there. Also pass the source device as it'd be expected, in the
input-induced crossing event generation paths.

The stage has the knowledge about input that is ongoing over it
(incl. things like styli and touchpoints). Add an iterator API
for these devices/touchpoints, so they can be used for calculations

The assertion for !implicit_grab_cancelled in the
`grab_actor == old_grab_actor` case of
clutter_stage_notify_grab_on_pointer_entry() is meant to do a simple
sanity-check to ensure the grab machinery is working as intended: During a
seat grab, all input gets delivered to the tree inside the grab, and all
implicit grabs outside of that tree are cancelled.
When a new seat grab on the same actor as the existing one happens, we run
through the cancellation machinery for implicit grabs anyway, so we might as
well check that the assumption mentioned above holds true: By asserting that
no implicit grabs were cancelled, we know that no implicit grabs exist
outside of the existing seat grab tree.
This assertion is slightly over-eager though due to the way we set
implicit_grab_cancelled: We initialize it to TRUE in the
entry->press_count > 0 case and then only set it to FALSE once we find an
implicit grab that may remain active. If there are no implicit grabs though
(while entry->press_count is still >0), we never set implicit_grab_cancelled
to FALSE, triggering the assertion in question even though no implicit grabs
got cancelled.
There's two possible solutions for this: Either dropping the assertion, or
refactoring it so it observes the situation where the implicit grabs were
already undone. This commit implements the latter.

Adds va_marshallers to the ClutterStage signals. This allows for better
stack traces to be retrieved when profiling. Additionally, since the
generic marshaller was using GBoxedCopy/GBoxedFree functions for the
GValue usage, the previous code was acquiring a global reader/writer
lock in GObject via g_boxed_free() usage.
With G_SIGNAL_TYPE_STATIC_SCOPE, the generated marshallers can avoid
the additional copy/free on the instance.

This adds some plumbing to get the "default" paint flags for regular
stage painting, where one either wants to paint the overlay, or not.
If inhibited, the 'no-cursors' paint flag is used, otherwise the 'none'
flag. This will be used to allow having a per stage view hw cursor
state.

An input only grab is a ClutterGrab on the stage that doesn't have an
explicit actor associated with it. This is useful for cases where event
should be captured as if focus was stolen to some mysterious place that
doesn't have anything in the scene graph that represents it.
Internally, it's implemented using a 0x0 sized actor attached directly
to the stage, and a clutter action that consumes the events. An
input-only grab takes a handler, user data and a destroy function for
the user data. These are handed to the ClutterAction, which handles the
actual event handling.

This will consist of device-added events, meaning before init finishes,
we can derive some state that depends on the set of input devices
available on startup, such as cursor visibility.
This avoids cursor visibility switching between hidden and visibility

We're using clutter_stage_schedule_update() now from ClutterActor to kick
off the stage updating machinery when a redraw needs to happen.
This introduced a bunch of unnecessary calls to
clutter_stage_schedule_update() and thus
clutter_stage_view_schedule_update() when multiple actors request redraws
during the same stage update cycle, which is a very common case.
Cut off all those unnecessary calls by bailing out in
clutter_stage_schedule_update() when updates are already queued.
