204 Formerly, we used PointerMotionHintMask (in standard_event_mask)
205 so that we would have to call XQueryPointer after each MotionNotify
206 event to ask for another such event. However, this made mouse tracking
207 slow, and there was a bug that made it eventually stop.
209 Simply asking for MotionNotify all the time seems to work better.
211 In order to avoid asking for motion events and then throwing most
212 of them away or busy-polling the server for mouse positions, we ask
213 the server for pointer motion hints. This means that we get only
214 one event per group of mouse movements. "Groups" are delimited by
215 other kinds of events (focus changes and button clicks, for
216 example), or by XQueryPointer calls; when one of these happens, we
217 get another MotionNotify event the next time the mouse moves. This
218 is at least as efficient as getting motion events when mouse
219 tracking is on, and I suspect only negligibly worse when tracking
