163 | Formerly, we used PointerMotionHintMask (in standard_event_mask) | |

165 | event to ask for another such event. However, this made mouse tracking | |
166 | slow, and there was a bug that made it eventually stop. | |

168 | Simply asking for MotionNotify all the time seems to work better. | |
169 | ||
170 | In order to avoid asking for motion events and then throwing most | |
171 | of them away or busy-polling the server for mouse positions, we ask | |
172 | the server for pointer motion hints. This means that we get only | |
173 | one event per group of mouse movements. "Groups" are delimited by | |
174 | other kinds of events (focus changes and button clicks, for | |
175 | example), or by XQueryPointer calls; when one of these happens, we | |
176 | get another MotionNotify event the next time the mouse moves. This | |
177 | is at least as efficient as getting motion events when mouse | |
178 | tracking is on, and I suspect only negligibly worse when tracking | |

8354 | where check_alarm in sysdep.c is called to simulate alarm signals. | |
