A finished gesture may have 2 possible outcomes, an event with phase
Gdk.TouchpadGesturePhase.END will be emitted when the gesture is
considered successful, this should be used as the hint to perform any
permanent changes.
Cancelled gestures may be so for a variety of reasons, due to hardware
or the compositor, or due to the gesture recognition layers hinting the
gesture did not finish resolutely (eg. a 3rd finger being added during
a pinch gesture). In these cases, the last event will report the phase
Gdk.TouchpadGesturePhase.CANCEL, this should be used as a hint
to undo any visible/permanent changes that were done throughout the
progress of the gesture.
