If a pointer is constrained by a pointer barrier, release the pointer
|
|
from the barrier and allow it to cross the barrier with the next motion.
|
|
If the pointer moves away from the barrier, this request does nothing.

This request only releases the pointer for the given barrier event
|
|
sequence. If the pointer moves away from or through the barrier, a
|
|
XI_BarrierLeave event is generated. Future pointer movement constrained
|
|
by this barrier will assign a new eventid and require a new
|
|
XIBarrierReleasePointer request.
