Indeed I did not have this correct if unrolling the first loop for X and Y (only two dimensions in 2D instead of 3 in 3D), then unroll the second loop. The second loop is addition of a.r[j] which means yes, it should be HalfWidth = xRadius * Abs(M11) + yRadius * Abs(M12). Similar for HalfHeight but with i=1.
