| 144 | event to ask for another such event. However, this made mouse tracking |
| 145 | slow, and there was a bug that made it eventually stop. |

| 149 | In order to avoid asking for motion events and then throwing most |
| 150 | of them away or busy-polling the server for mouse positions, we ask |
| 151 | the server for pointer motion hints. This means that we get only |
| 152 | one event per group of mouse movements. "Groups" are delimited by |
| 153 | other kinds of events (focus changes and button clicks, for |
| 154 | example), or by XQueryPointer calls; when one of these happens, we |
| 155 | get another MotionNotify event the next time the mouse moves. This |
| 156 | is at least as efficient as getting motion events when mouse |
| 157 | tracking is on, and I suspect only negligibly worse when tracking |
