Hi Thorsten Froehlich, you recently wrote in
povray.unofficial.patches:

That is computationally much too expensive. Since the antialiasing has
already been done by making a mipmap, it is not neccessary to fire
extra rays. And once you start getting far away you would have to
antialias far too many rays.
