Et tu, Photoshop?

Does anyone know whether GIMP and ImageMagick do it correctly?  The 
article doesn't mention these two, but I use them for resizing, and I've 
wondered about this issue.

I'm confident that POV-Ray 3.7 does it correctly, but who wants to write 
a scene file just to resize?  (I often end up doing that for simple 
editing anyway, because it's easier than deciphering the GIMP 
documentation.)

POV-Ray 3.6.2 and earlier read image files incorrectly, although this 
can be fixed with a pigment function, which is what I did before 3.7 was 
developed.  (Thanks Jaime or Ive, whoever posted the function.)  The 
article might also explain why anti-aliased text in POV-Ray 3.5 looks 
heavier than in 3.6 and later.
