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