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