Copperbox revision 1482.

Preliminary reworking for the Primitive affine transformations code...

The instances of the affine classes (Scale, Rotate...) that I added for Primitives in version 0.18.0 turn out to be unworkable. This is perhaps not surprising as transforming Primitives doesn't really take place in an affine frame / affine space, but I had overlooked this and the code doesn't work properly.

This revision was a quick attempt at rectifying the problems, but it is unsatisfactory, and I will roll back most of the changes here. I committing it so the HEAD will at least include an acknowledgement that there is a problem.
