9-- A list of touches. Each ongoing touch is represented by a set of
10-- coordinates and an identifier id that allows you to distinguish
11-- between different touches. Each touch also contains the coordinates and
12-- time of the initial contact (x0, y0, and t0) which helps compute more
13-- complicated gestures.
