That's not so. Any affine transform is a linear transformation, and rotation around a point can certainly be represented as an affine transform. Most likely the reason why NSAffineTransform doesn't have this functionality is because NSAffineTransform simply provides the basic building blocks, and rotation about a point is actually a combination of those basics.
