Naively moving the old code over the new system hits a
little gotcha: the "rotation()" call in Transform actually performs a full SVD
to extract the scale component from the linear part:
This is an aside, but if have a general transform, is doing Jacobi SVD the
fastest? Did anyone investigate using the newton type methods? eg.
