Accept touch sequence for pointer listener after second event delivery
This is a bit of unimplemented code for touchscreen pointer emulation. A pointer grabbing client currently never accepts the touch sequence. The sequence must be accepted once any touch-derived event is irrevocably delivered to a client. The first pointer event, derived from a touch begin event, may be caught in a sync grab and then replayed. This is essentially a revocable delivery of an event. Thus, we must wait till a non-begin event is delivered. Signed-off-by: Chase Douglas <chase.douglas@canonical.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net>
