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