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