1610 | In order to avoid asking for motion events and then throwing most | |

1614 | other kinds of events (focus changes and button clicks, for | |

1616 | get another MotionNotify event the next time the mouse moves. This | |
e5d77022 | 1617 | is at least as efficient as getting motion events when mouse |
