This function may be used on key events to obtain the fully
detailed pressed/latched/locked modifiers that apply when the
event is received. No events have this detailed information
yet.
This API call may be compared to the clutter_event_get_state_full()
that existed in the past, although this getter has a stronger
predilection to it applying exclusively to key events.

All ClutterEvent users have been changed to use getter methods
instead of direct field access. We may now make the ClutterEvent
union/structs entirely opaque by moving the definitions out of
public headers.
All future usage of ClutterEvent data should be done through
getter methods.

Add methods, and change the API of some rarely used methods, in order
to make all event info currently held/necessary accessible through
ClutterEvent getters, instead of direct field access.

The full decomposed modifier state is pretty much unused, relying
in keymap signals/properties to track latched modifiers state instead.
The events can be simplified without having this information, and if
it were ever needed in the future, it would be nicer that it had a
dedicated struct and didn't increase the number of arguments in
ClutterEvent constructors.

When a relative pointer motion gets constrained (e.g. a monitor edge or
barrier), save the constrained relative motion delta too.
This will later be used to send the remaining motion delta to input
capture clients.

The source field was removed from ClutterEvent with commit
b644ea1bce because the preferred way of
getting the event actor is now to use the device/sequence actor from the
stage directly.
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
on a crossing event.

We'll need the additional context of which actor the event will be
emitted to in mutters event filter (see next commit), so pass that
target actor to the event filters that are installed.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2321>
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 does two things to frown upon:
- Modifies ClutterEvent structs, while the effort is to have those
completely opaque, and readonly after creation from the input
thread side.
- Stores state in the ClutterInputDevice struct, event though those
are also considered static after creation, managed by the input
thread, etc.
Stop doing that. This makes all events just forwarded as-is in
the ClutterStage/clutter-main.c code.
Handling of click count sounds like material for a ClutterGestureAction
(or perhaps ClutterClickAction), all of both callers now do it in place
at the moment, while gestures lack a better state tracking and management.

This mode is passed along by the ClutterInputMethod, the
ClutterInputFocus will preserve it and ensure it is honored
whenever the IM is being reset.
This mode is immediate. The ClutterInputFocus commits the
text directly without queueing a CLUTTER_IM_COMMIT event.
This is important so events are serialized in the right order
in the wayland implementations (i.e. commit before wl_pointer.press).

Instead of using native backend platform data specifically, store
this info in ClutterMotionEvent. This includes time in usec since
it's just used for motion events, in the future it could make sense
to make these general to all events again, but it could make sense
to make ClutterEvent structs private before.
In order to express that a motion event has relative motion info,
the CLUTTER_EVENT_FLAG_RELATIVE_MOTION event flag has been added
for it.

We had code in both backends that sort of independently associated
sequences to slots. Make both transform slots to sequences the same
way, so they may share the implementation convert those back to slots.
This helper now lives in Clutter API.

We have this as platform-dependent data in the native backend, and
a bunch of fallback code done in place in the evcode users. Stop
making this platform-dependent data, and move it to the relevant
ClutterEvents.
The fallback code for the X11 backend case is about the same, but
now it is done directly by the X11 backend.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1623>
Making this an event is overly convoluted, accounting that we
emit the event, then convert it to a ClutterStage signal, then
its only consumer (a11y) sets the active ATK state.
Take the event out of the equation, unify activation/deactivation
of the stage in MetaStage, and use it from the X11 backend too.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1623>
Add clutter device added and removed events to allow processing of them as
it happens in the backends, queuing them and performing actions in order.
This allows not to loose any event that is performed just before removing or
disabling a device, and still process the events in order in the event
queue.

When the pointer is grabbed, we send the crossing events that are
initiated by this pointer only to the actor that has the grab. For
grabbed touch sequences, we always capture and bubble the crossing
events right now.
Fix this and make grabbed pointers and touch sequences behave the same
by sending touch crossing events only to the grab actor.

Those map closely what we get from libinput. Button events have
been made its own separate struct, its semantics fall somewhere
in between of ClutterButtonEvent and ClutterKeyEvent, so is better
emitted as its own set.
