Either I'm confused about the use of GrabPointer, or I've hit
a bug.  Or both.  I'd be glad if someone would enlighten me.

According to the protocol, when a GrabPointer is requested
with owner-events == False, "all generated pointer events...are
only reported if selected by event-mask".  Now, this implies
to me that regardless of the events selected on my windows (by
SelectEvent) I should get only events selected by the
event-mask in the GrabPointer call.  In my case, the
event-mask==ButtonPressMask, yet I still get EnterNotify's and
MotionNotify's.

If someone has an explanation, I'd be thankful for it.

See you in Boston.
