-/* Mouse movement. Rah.
-
- In order to avoid asking for motion events and then throwing most
- of them away or busy-polling the server for mouse positions, we ask
- the server for pointer motion hints. This means that we get only
- one event per group of mouse movements. "Groups" are delimited by
- other kinds of events (focus changes and button clicks, for
- example), or by XQueryPointer calls; when one of these happens, we
- get another MotionNotify event the next time the mouse moves. This
- is at least as efficient as getting motion events when mouse
- tracking is on, and I suspect only negligibly worse when tracking
- is off.
-
- The silly O'Reilly & Associates Nutshell guides barely document
- pointer motion hints at all (I think you have to infer how they
- work from an example), and the description of XQueryPointer doesn't
- mention that calling it causes you to get another motion hint from
- the server, which is very important. */
