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

231 | ||
69388238 RS |
232 | In order to avoid asking for motion events and then throwing most |
233 | of them away or busy-polling the server for mouse positions, we ask | |
234 | the server for pointer motion hints. This means that we get only | |
235 | one event per group of mouse movements. "Groups" are delimited by | |
236 | other kinds of events (focus changes and button clicks, for | |
237 | example), or by XQueryPointer calls; when one of these happens, we | |
238 | get another MotionNotify event the next time the mouse moves. This | |
239 | is at least as efficient as getting motion events when mouse | |
240 | tracking is on, and I suspect only negligibly worse when tracking | |
