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