Are their any mice out there that actually have a z axis?  The reason
for that mapping command, of course, is that the mice provide a pair
of buttons with a "funny connector" rather than an actual z axis wheel.

So that mapping has to happen *somewhere*.

I beleive it should be xset(1x)able, and that apps should be looking
for buttons rather than an axis for scrolling.  The Z axis should be
left for 3d use.

Alternatively, new axes could be defined, such as the vertical scroll
axis, the horizontal scroll axis, etc.  In any case, on-the-fly per-
pointer mucking of what x event each button and each axis generates
is useful and should be a support target.
