146 Formerly, we used PointerMotionHintMask (in standard_event_mask)
147 so that we would have to call XQueryPointer after each MotionNotify
148 event to ask for another such event. However, this made mouse tracking
149 slow, and there was a bug that made it eventually stop.
151 Simply asking for MotionNotify all the time seems to work better.
153 In order to avoid asking for motion events and then throwing most
154 of them away or busy-polling the server for mouse positions, we ask
155 the server for pointer motion hints. This means that we get only
156 one event per group of mouse movements. "Groups" are delimited by
157 other kinds of events (focus changes and button clicks, for
158 example), or by XQueryPointer calls; when one of these happens, we
159 get another MotionNotify event the next time the mouse moves. This
160 is at least as efficient as getting motion events when mouse
161 tracking is on, and I suspect only negligibly worse when tracking
