251 // upper 2x2 is scale + rotation/reflection if basis vectors are orthogonal
1450 // if upper left 2x2 is orthogonal save some math
1666 // an orthogonal matrix Q and a symmetric matrix S. In turn we can decompose S into U*W*U^T,
1667 // where U is another orthogonal matrix and W is a scale matrix. These can be recombined
1668 // to give M = (Q*U)*W*U^T, i.e., the product of two orthogonal matrices and a scale matrix.
