181 Formerly, we used PointerMotionHintMask (in STANDARD_EVENT_MASK)
182 so that we would have to call XQueryPointer after each MotionNotify
183 event to ask for another such event. However, this made mouse tracking
184 slow, and there was a bug that made it eventually stop.
186 Simply asking for MotionNotify all the time seems to work better.
188 In order to avoid asking for motion events and then throwing most
189 of them away or busy-polling the server for mouse positions, we ask
190 the server for pointer motion hints. This means that we get only
191 one event per group of mouse movements. "Groups" are delimited by
192 other kinds of events (focus changes and button clicks, for
193 example), or by XQueryPointer calls; when one of these happens, we
194 get another MotionNotify event the next time the mouse moves. This
195 is at least as efficient as getting motion events when mouse
196 tracking is on, and I suspect only negligibly worse when tracking
