RotateFlyFrame3: Initial support added
First steps to get a rotated FlyFrame and content
that only uses layouted sizes/positions and does not
change the model data (except rotation). This works
with persistence, after reload the rotation can be
resetted with going back to the original FrameSize.
Lot of stuff not yet working, experimental state.
