This gesture handles any number of clicks, ensuring multiple presses stay within thresholds and timeouts. When anything of that happens, the gesture is reset and press count starts from 1 again. Optionally, the gesture can be given a rectangle, used in in presses > 1 to ensure the consecutive presses happen on user imposed areas.
