The emulated mice should emulate a horizontal wheel when possible. This
patch series does that for the USB mouse and tablet and the ExPS/2
mouse. As far as I can tell the vmmouse protocol doesn't handle a
horizontal wheel, and I have no idea if emulating a wheel might make
sense for any of the other mouse types.
At this point, are we just talking about adding additional mouse buttons?
I think instead of adding an additional parameter for horizontal wheel,
we should look at making the API capable of accepting/generating
arbitrary button presses.
Really, we should just drop dz and treat vertical wheel as two button
presses within button_state. Likewise, horizontal wheel should just be
two additional bits within button_state.

I've tested this using the SDL interface and an Ububtu 10.04 cd image;
xev reports the correct events for all three devices, and a gedit window
with sufficient text to create scrollbars scrolls correctly with both
mice (didn't test the tablet). More testing would be good.
