Kees Cook was also working on patch to g-s-d to solve this problem on
his laptop at UDS.  IIRC, he'd also implemented it using xsetwacom, but
we'd also talked about the changes to xinput; I don't know if he updated
his patch for that, but I'm CCing him.

Kees - mind pointing us to your tablet rotation patch?  Would at least
be interesting to have it to compare with Federico's code.
