Let's cross fingers and hope nobody notices. If this went unnoticed so far, likely
means this function has never been used. If any complain is raised about this, a
stub function should be added (and marked deprecated).
When the threshold-trigger-edge property was introduced in
GestureAction, it was late in the cycle and I elected to keep it
private, given the fact that nobody was subclassing GestureAction
outside of Clutter itself.
These days, people are experimenting more with the GestureAction API, so
they will need access to the various knobs that control the class
default behaviour.

Export the last event received for each touch point in its entirety,
instead of duplicating ClutterEvent accessors one at a time.
examples/pan-action.c has been updated to show the type of the event
that's causing the panning.

Add some accessors to simplify common tasks for GestureAction users:
• clutter_gesture_action_get_motion_delta() to get the delta
on the X and Y axis in stage coordinates since the last motion
event, and the scalar distance travelled;
• clutter_gesture_action_get_velocity() to get an estimate of the
speed of the last motion event along the X and Y axis and as a
scalar value in pixels per millisecond.

GestureAction supports a single device/touch point. We'll need touch
events supported in Clutter before adding the ability to set required
device/touch points on gestures.

The GestureAction is marked as abstract, but it has a constructor. It
should be possible to create simple gesture recognizers through signal
handling alone, so we might as well have GestureAction be a concrete
class from the start.
