 * This is a subclass of Gesture, optimized (although
 * not restricted) for dealing with mouse and single-touch gestures. Under
 * interaction, these gestures stick to the first interacting sequence, which
 * is accessible through get_current_sequence() while the
 * gesture is being interacted with.
 *
 * By default gestures only react to touch events. set_touch_only()
 * can be used to change this default behavior. Callers may also specify
 * a mouse button number to interact with through set_button().
