Yeah, sure.  That was just to show the point (it's more explicit to
show the result of the parsing of the loop than to show the loop).

  Anyway, I would not do it with a #while loop, rather with a Perl
program.  If I ever need to write such a program, I guess it could
easily be made universal enough so that it be able to take any POV-Ray
scene file (with the textures and all) and change everything to the
convenient z-buffer texture.  No need to make it by hand!

But size of color_map is limited.
