For now, I've re-added Michael Thaler's special scaling code and special cased
it for rgba8, cmyk8 and graya8. The results are, as far as I can see, superior
to nearly everything else. Diff attached in case Cyrille wants to add this to 
the tag for 1.6.1 (which I'd advise, because it's tested code and does work 
beautifully).

Unless we can fix the generic transform code to give results at least as good 
as this code for scaling down, I'll transport it to trunk, too.
