I think this point has been addressed in a previous message to this list, but
I've forgotten the answer and I can't find it anywhere in the Xv11 protocol
specification.

If a client selects both ButtonPress and ButtonRelease events for window W, and
receives a ButtonPress event with W as the "source", is he guaranteed also to
receive a ButtonRelease event with W as the "source" (regardless of the position
of the pointer at the time of the button's release)?  Would this occur even if
the client had *not* selected ButtonRelease events for window W?  In the case
that the pointer is in window Y at the time of the button's release, is a
ButtonRelease event with Y as the "source" also sent to interested clients?
