  17. It should be pointed out that a normal non-fractal zoom will not generate
  18. blocky, square pixels if it is done properly.  With antialiasing, the zoomed
  19. image will remain smooth.  (There will, of course, be no detail in the zoomed
  20. areas.)  Thus, it is a misleading comparison to say that fractal zooming is
  21. better because you don't get big blocky pixels.
