frame width/height and box-sizing

[thomashandorf]

the frame width is calculated wrongly if paddings and borders are applied. This could in principle be fixed by setting border-box on all frames but this may have impact on the users css code. so ideally calcFrameTransform will detect which box sizing is in effect and will use the right width/height anyway.

Maybe it would be better if the width() and height() methodes detect this automatically.

yes, makes sense
