3852 Formerly, we used PointerMotionHintMask (in standard_event_mask)
3853 so that we would have to call XQueryPointer after each MotionNotify
3854 event to ask for another such event. However, this made mouse tracking
3855 slow, and there was a bug that made it eventually stop.
3857 Simply asking for MotionNotify all the time seems to work better.
3859 In order to avoid asking for motion events and then throwing most
3860 of them away or busy-polling the server for mouse positions, we ask
3861 the server for pointer motion hints. This means that we get only
3862 one event per group of mouse movements. "Groups" are delimited by
3863 other kinds of events (focus changes and button clicks, for
3864 example), or by XQueryPointer calls; when one of these happens, we
3865 get another MotionNotify event the next time the mouse moves. This
3866 is at least as efficient as getting motion events when mouse
3867 tracking is on, and I suspect only negligibly worse when tracking
