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