* ClutterTouchpadHoldEvent
* @type: event type
* @time: event time
* @flags: event flags
* @stage: event source stage
* @source: event source actor (unused)
* @phase: the current phase of the gesture
* @n_fingers: the number of fingers triggering the swipe
* @x: the X coordinate of the pointer, relative to the stage
* @y: the Y coordinate of the pointer, relative to the stage
*
* Used for touchpad hold gesture events. The current state of the
* gesture will be determined by the @phase field.
*
* A hold gesture starts when the user places one or many fingers on the
* touchpad and ends when all fingers are lifted. It is cancelled when the
* finger(s) move past a certain threshold.
* Unlike swipe and pinch, @phase can only be
* CLUTTER_TOUCHPAD_GESTURE_PHASE_BEGIN, CLUTTER_TOUCHPAD_GESTURE_PHASE_END and
* CLUTTER_TOUCHPAD_GESTURE_PHASE_CANCEL.
