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