  You probably don't want mipmapping alone, because all by itself it's
pretty useless (well, not useless, but it causes a very visible abrupt
change at the places where the mipmap level changes). What you want
is trilinear interpolation.
  Unfortunately POV-Ray does not support that. There are a couple of
problems implementing trilinear interpolation in a raytracer. They can
probably be solved, but it's not as trivial as in a scanline renderer.
