Formerly, we used PointerMotionHintMask (in standard_event_mask)
so that we would have to call XQueryPointer after each MotionNotify
event to ask for another such event. However, this made mouse tracking
slow, and there was a bug that made it eventually stop.
Simply asking for MotionNotify all the time seems to work better.
In order to avoid asking for motion events and then throwing most
of them away or busy-polling the server for mouse positions, we ask
the server for pointer motion hints. This means that we get only
one event per group of mouse movements. "Groups" are delimited by
other kinds of events (focus changes and button clicks, for
example), or by XQueryPointer calls; when one of these happens, we
get another MotionNotify event the next time the mouse moves. This
is at least as efficient as getting motion events when mouse
tracking is on, and I suspect only negligibly worse when tracking
is off. */
