Robert Osfield a799cdca2f From Tim Daust, "I fixed the getScale functions in matrixf and
matrixd.  It was returning the values of the diagonal
of the matrix, which only returns the scale if there
is not a rotation.  I fixed this by returning the
length of the  vectors that form the basis.
  I also added a function to orthonormalize the
rotation component of the matrix. I seem to always run
into situations where non uniform (or even uniform)
scale complicate my calculations, and I thought other
members of the community could use this function as
well."
