Does anyone know how Nokia's PR1.2 rotation is implemented?

Because when using the Ctrl + Shift + R the apps actually pivot correctly and reformat to fit portrait (well most of them do) whereas with the rotate.py and rotate_app there is no reformatting done and it just only shows half the width???

Surely someone can find out how nokia implemented rotate by studying how the phone/browser app rotates and then implement this method into the rotate_app or the rotate.py script??

Im just asking I aint demanding anything I have no clue how to do this stuff, I consider myself an advanced user but I do not have any linux/python experience

Thanks
