What kind of results are you seeing?
essentially what I did was change DeviceSetTransform() to write the
matrix in as-is for relative devices (skipping scale and transform) and
use transformAbsolute() in GetPointerEvents for relative events. That
calculated the right values, but acceleration was off, the movement
wasn't consistent with the pointer sometimes feeling like stuck in goo.
It was a quick hack to try it, but that's what I meant with "not quite
as trivial"
Cheers,
Peter

I'm afraid I've gotten caught up with all kinds of other work, so I
haven't done any more work on it yet :/
I still plan on doing work on it and push coordinate transform matrix
support to the upper (E.G. gnome-display-properties) layers, but I don't
have any hard timeline.
