@NiLuJe:

I've attached a binary of Plato that should run on the Sage.
It was slightly modified so that the initial view is Rotation Values.

Please follow the instructions and post the resulting eight lines of the form Tap (X, Y) (W, H) that you'll find at the end of info.log.

EDIT: The application now logs the inferred startup rotation and mirroring scheme (I've updated the binary).
