--- Comment #1 from C. Boemann <cbo@boemann.dk> ---
So much confusion in the comments.

Boundingbox is in document coordinates and view aligned and should only be used
for finding parts of the screen that needs updating.

Outline is what the shape manipulation tool draws around the shape when
rotating. The outline is specified in shape coordinates.

The poster is correct in modifying the bounding box, though it should be done a
bit earlier in the code i feel. so scaling etc would also happen to the width.

Bounding box should _never_ be used for calculating (eg aligning shapes). If
that is still done it should be fixed. If someone is not convinced: bounding
box even includes shadow and filter effect
