Hi Bastian,

I tried testing out these patches, but they almost immediately fell
flat on their face. A pointer appears and moves around when I bring my
pen into prox, and disappears when it leaves prox. When I bring the
pen into prox a second time, however, weston either hangs or crashes.
For what its worth, I did test this patchset the last time they were
posted to the list and didn't encounter this problem.

I've attached a hid-replay log of my Intuos Pro which will hopefully
let you reproduce the issue yourself. I can try to provide coredumps
or backtraces instead if you'd prefer.

Jason
