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