-- An event related to a gesture on a touchpad device.
-- 
-- Unlike touchscreens, where the windowing system sends basic
-- sequences of begin, update, end events, and leaves gesture
-- recognition to the clients, touchpad gestures are typically
-- processed by the system, resulting in these events.
