tdf#145904,tdf#145956 improve extrusion of custom shapes

The patch addressed these errors:
The property Origin is relative to the bounding rectangle of the shape
not to the snap rectangle. That error is visible e.g. for a block arc.
Rotation center x- and y- values are relative to the snap rectangle and
not absolute.
Rotation center z-value is in Hmm and needs conversion to Twips in
Writer.
Rotation is around rotation center, which might be different from shape
center. That has been ignored.

I have moved calculation of the 2D logic rectangle of the scene to
main method to be able to reuse the transformation and other values.
I consider using a special local class as unneeded overhead.

I have reordered some parts to bring geometry relevant parts together.
