155 | Formerly, we used PointerMotionHintMask (in standard_event_mask) | |
156 | so that we would have to call XQueryPointer after each MotionNotify | |
157 | event to ask for another such event. However, this made mouse tracking | |
158 | slow, and there was a bug that made it eventually stop. | |

161 | ||
162 | In order to avoid asking for motion events and then throwing most | |
163 | of them away or busy-polling the server for mouse positions, we ask | |
164 | the server for pointer motion hints. This means that we get only | |
165 | one event per group of mouse movements. "Groups" are delimited by | |
166 | other kinds of events (focus changes and button clicks, for | |
167 | example), or by XQueryPointer calls; when one of these happens, we | |
168 | get another MotionNotify event the next time the mouse moves. This | |
169 | is at least as efficient as getting motion events when mouse | |
170 | tracking is on, and I suspect only negligibly worse when tracking | |
