[PATCH libinput 2/3] Implement support for pen barrel rotation

[Bill Spitzak]

Why not call it Z instead of TWIST?

I'm pretty certain that is a common term for this movement, and that 
"twist" is a rather strange term ("roll" is used more). And Z has the 
advantage that it also implies that counter-clockwise is positive.
