Fade out the mouse pointer after inactivity or other events.
Fades out the mouse pointer:
- after 15 seconds of inactivity normally
- after 3 seconds of inactivity in lights out mode
- after a non-modifier key down
- after a touch down
Extended the native Looper to support enqueuing time delayed
messages. This is used by the PointerController to control
pointer fade timing.
