valuators == device axes.

the actual communication between a driver and the X server is relatively
simple, it's basically all the xf86PostXYZEvent functions in xf86XInput.c.

assuming that your device is set up correctly and you're passing valid data
(i.e. data from valuators that have been initialised and the data falls into
the min/max range), the server should do the rest.
