ABS_THROTTLE:
Tablets still advertise this axis but the mouse itself isn't available
anymore. The Pad sends the second wheel as ABS_THROTTLE but that's a
task for the buttonset interface. Explanation of what the throttle
did on page
http://101.wacom.com/productsupport/manual/Intuos2UsersManual.pdf
ABS_RX/ABS_RY:
These only happen on the Intuos3 device and only on the Pad device
(kernel >= 3.17)
ABS_RZ:
The 4D mouse for the Intuos2, obsolete.
No functional changes, this is to clarify why we're only handling a subset of
codes.
