4645 Formerly, we used PointerMotionHintMask (in standard_event_mask)
4646 so that we would have to call XQueryPointer after each MotionNotify
4647 event to ask for another such event. However, this made mouse tracking
4648 slow, and there was a bug that made it eventually stop.
4650 Simply asking for MotionNotify all the time seems to work better.
4652 In order to avoid asking for motion events and then throwing most
4653 of them away or busy-polling the server for mouse positions, we ask
4654 the server for pointer motion hints. This means that we get only
4655 one event per group of mouse movements. "Groups" are delimited by
4656 other kinds of events (focus changes and button clicks, for
4657 example), or by XQueryPointer calls; when one of these happens, we
4658 get another MotionNotify event the next time the mouse moves. This
4659 is at least as efficient as getting motion events when mouse
4660 tracking is on, and I suspect only negligibly worse when tracking
