228 | In order to avoid asking for motion events and then throwing most |

231 | one event per group of mouse movements. "Groups" are delimited by | |
232 | other kinds of events (focus changes and button clicks, for | |
233 | example), or by XQueryPointer calls; when one of these happens, we | |
234 | get another MotionNotify event the next time the mouse moves. This | |

236 | tracking is on, and I suspect only negligibly worse when tracking | |
