4723 Formerly, we used PointerMotionHintMask (in standard_event_mask)
4724 so that we would have to call XQueryPointer after each MotionNotify
4725 event to ask for another such event. However, this made mouse tracking
4726 slow, and there was a bug that made it eventually stop.
4728 Simply asking for MotionNotify all the time seems to work better.
4730 In order to avoid asking for motion events and then throwing most
4731 of them away or busy-polling the server for mouse positions, we ask
4732 the server for pointer motion hints. This means that we get only
4733 one event per group of mouse movements. "Groups" are delimited by
4734 other kinds of events (focus changes and button clicks, for
4735 example), or by XQueryPointer calls; when one of these happens, we
4736 get another MotionNotify event the next time the mouse moves. This
4737 is at least as efficient as getting motion events when mouse
4738 tracking is on, and I suspect only negligibly worse when tracking
