1641 | In order to avoid asking for motion events and then throwing most | |

1643 | the server for pointer motion hints. This means that we get only | |
1644 | one event per group of mouse movements. "Groups" are delimited by | |
1645 | other kinds of events (focus changes and button clicks, for | |
1646 | example), or by XQueryPointer calls; when one of these happens, we | |
1647 | get another MotionNotify event the next time the mouse moves. This | |
e5d77022 | 1648 | is at least as efficient as getting motion events when mouse |
90e65f07 JB |
1649 | tracking is on, and I suspect only negligibly worse when tracking |
1650 | is off. | |
