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

-- The last position that was tapped. Default value is `{x=0,y=0}`.
-- Updates whenever the user taps the screen.
