06a2c219 | 305 | Formerly, we used PointerMotionHintMask (in standard_event_mask) |

314 | the server for pointer motion hints. This means that we get only | |
315 | one event per group of mouse movements. "Groups" are delimited by | |
316 | other kinds of events (focus changes and button clicks, for | |
317 | example), or by XQueryPointer calls; when one of these happens, we | |
318 | get another MotionNotify event the next time the mouse moves. This | |
