[metapost] CMYK is beautifull

[L. Nobre G.]

Hi all,

FeatPost uses "color"s as positions in 3D-space,
now guess what can be done with both "cmykcolor"s and "filenametemplate"...

The latest MetaPost version runs the following code:
-----------------------------------------------------------------------------------
filenametemplate "%j%4c.eps";
beginfig(1);
  cmykcolor b, c, d;
  b = (1,1,1,1);
  c = (0,0,0,4000);
  if cmykcolor c:
    message "c is a cmykcolor";
  fi;
  message "b=";
  show b;
  message "c=";
  show c;
  d = 0.5[c,b];
  message "d is the average of c and b";
  show d;
  message "the magenta part of d:";
  show magentapart d;
endfig;
end.
