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.
