321 | so that we would have to call XQueryPointer after each MotionNotify |

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