RotGrfFlyFrame: Adapt Crop functionality to rotated Graphic
The FlyFrame which may contain a Graphic needs working Crop,
interactive and in core. Adapted this to work with now possible
rotation, changed common code in svx which has to handle cases
for Draw/Impress/Calc and Writer differently. Tried to use as
much in common as possible. Additionally furter adaptions
to rotation itself.
