I'm not sure, whether a 90 degree rotation is easier. There is no 
problem to rotate the image. That can already be easily done with a 
simple matrix transformation. But you need to change the area into which 
the image is drawn. And that problem exists for a 90 degree rotation as 
well. You cannot rotate the image itself and insert a new rotated one, 
because the image might be linked and not embedded. Do you know, how 
that would be solved for a 90 degree rotation?

I have already tried to change area into which the image is drawn by 
setting suitable crop values. But currently there are heavy display 
problems, when using negative values there. The problems with negative 
values exists independent of any rotation, try it in the dialog.

Kind regards
