RotateFlyFrame3: Corrected interactive Crop

To correct interactive Crop in transformed states, I had to
rework some stuff involved that anyways was in a non optimal
state. Added functionality to translate the object to make
Crop seem to work more seamlessly. Some mapping was needed
to make the Cropped, transformed object to be in the correct
relative position to the uncropped, untransfomed one.
Restructured TransformableSwFrame to directly re-create
last non-transformed SwFrame(s) from the SwFrameAreaDefinition
from the current Transformations, offering the untransformed
SwRect(s) now for usage.
Identified and corrected error when FlyFrame was translated
using keyboard, the accessing method needed to adapt position
in the transformed case.
Started to look at Contour stuff, adapted a set contour to be
correctly used by adapting it as needed in the transformed case.
