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