4636 Formerly, we used PointerMotionHintMask (in standard_event_mask)
4637 so that we would have to call XQueryPointer after each MotionNotify
4638 event to ask for another such event. However, this made mouse tracking
4639 slow, and there was a bug that made it eventually stop.
4641 Simply asking for MotionNotify all the time seems to work better.
4643 In order to avoid asking for motion events and then throwing most
4644 of them away or busy-polling the server for mouse positions, we ask
4645 the server for pointer motion hints. This means that we get only
4646 one event per group of mouse movements. "Groups" are delimited by
4647 other kinds of events (focus changes and button clicks, for
4648 example), or by XQueryPointer calls; when one of these happens, we
4649 get another MotionNotify event the next time the mouse moves. This
4650 is at least as efficient as getting motion events when mouse
4651 tracking is on, and I suspect only negligibly worse when tracking
