XInput transform matrix

[Cedric Sodhi]

Can anyone tell me which transform matrix (prop 133 in XI) I have to
choose so that my touchscreen lines up with my 90 ccw rotated display?
I've tried practically everything I found sensible but I got absolutly
no useful results. In fact I get a jumping and flickering cursor, which
also maps differently based upon which direction I move in.

Could you help?

Thank you
