There was an argument that:
if (matrix.isInvertible())
matrix.invert();
would force UAs to compute the determinant twice. Actually, UAs can be very
smart about that. The determinant is a simple double. It can be stored and
invalidated as needed internally. (If it even turns out to be an issue.)
Maybe not even invalidated, but just kept up-to-date (e.g. determinant
of product = product of determinants)?
