invertAffine into out (12 numbers), reading the matrix from offset in objectToWorld, without allocating: for the
scene copy's per-instance writes, which setTransforms makes thousands
of a frame. Returns the determinant, or 0 when the matrix is singular or
the result isn't finite (then out holds garbage).
