33 * When a rotation gesture is detected, this structure holds information regarding the gesture.
35 * A Rotation Gesture event should be in one of four states:
36 * - Started: If a rotation is detected.
37 * - Continuing: If after a rotation is detected, it continues.
38 * - Finished: If after a rotation, the user lifts their finger(s).
39 * - Cancelled: If there is a system interruption.
