Event handling should only apply to editable ClutterText actors, but we
also have the :selectable property to care about.
The button/touch press should position the cursor inside an editable
ClutterText; the :selectable property should be used to allow selecting
the text, either through pointer or touch dragging, via the keyboard, or
by multiple pointer clicks. If neither of these two conditions are met,
the ClutterText should just propagate the event handling further.
Allow setting a ClutterRect on the drag action and force the
dragged actor's position to be always within that rectangle (relative
to the actor's parent).

The boolean_handled accumulator will stop the signal emission if TRUE is
returned by a signal handler; the boolean_continue accumulator will stop
the signal emission if FALSE is returned. The first one is used for
event-related signals, while the latter is used for action-related
signals.
Only the signal connection. When using G_ENABLE_DIAGNOSTIC there will be
a warning for every signal connection.
We should try and discourage people from ever using the paint signal
ever again, until we can safely remove it in Clutter 2.0.
The current versions redraws all events on every redraw, which starts
getting very slow quickly. Instead simply draw only the new events
except when the cairo surface got reset, in that case redraw all events
again.

We cannot fully deprecate Geometry, because ClutterActor and ClutterText
are actually using the type in signals and properties; but we can
deprecate the API that uses this type, so that 2.0 will be able to avoid
it entirely.
The :clip property still uses ClutterGeometry, which is a very bad
rectangle type. Since we cannot change the type of the property
compatibly, we should introduce a new property using ClutterRect
instead. This also matches the ClutterActor.set_clip() API, which uses a
decomposed rectangle with floating point values, like we do with
set_position() and set_size().
Instead of only relying on the (now) deprecated BinAlignment.FIXED
enumeration value, we just ask the actor if a fixed position has been
explicitly set, under the assumption that if a developer decided to call
set_x(), set_y(), or set_position() on an actor inside a BinLayout then
she wanted the fixed position to be honoured.
This removes the last (proper) use of the BinAlignment enumeration.
The Geometry type is an *awful* representation of a integer rectangle,
as it uses unsigned integers for its size, leading to overflow issues
when unioning and intersecting. We have better rectangle types in
Cairo and Clutter, these days.
Not every single one, but things that we care about to avoid breaking
build on other platforms, or for security issues, should not be allowed.
We should not force everyone to use -Werror, though; and we should still
allow building Clutter without any special flag.
In order to identify whether the crossing event is an enter or a leave,
we should use the ClutterEventType enumeration, not attach a value to
the signal handler.
When dragging/scrolling using touch events, we want the same behaviour
than for motion events. We need to honor the user's calls to
clutter_stage_set_motion_events_enabled() to deactive event
bubbling/captured sequences on the actor located under the pointer and
just transmit events to the stage/grab actor.

We need to make sure that ClutterActor::transition-stopped is emitted
after the transition was removed from the actor's list of transitions.
We cannot just remove the TransitionClosure from the hash table that
holds the transitions associated to an actor, and let the
TransitionClosure free function stop the timeline, thus emitting the
::transition-stopped signal - otherwise, stopping the timeline will end
up trying to remove the transition from the hash table, and we'll get
either a warning or a segfault.
Since we know we're removing the timeline anyway, we can emit the signal
ourselves in case the timeline is playing, in both the implicit and
explicit cases.
