public enum TouchpadGesturePhase
The phase of a touchpad gesture event.
A finished gesture may have 2 possible outcomes, an event with phase 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 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 with report the phase CANCEL, this should be used as a hint to undo any visible/permanent changes that were done throughout the progress of the gesture.
