Touch events are grouped into sequences by means of the sequence
field, which can also be obtained with gdk_event_get_event_sequence().
Each sequence begins with a Gdk.EventType.TOUCH_BEGIN event, followed by
any number of Gdk.EventType.TOUCH_UPDATE events, and ends with a Gdk.EventType.TOUCH_END
(or Gdk.EventType.TOUCH_CANCEL) event. With multitouch devices, there may be
several active sequences at the same time.
