As it stands now, I create the thumbnails as a CGImages inside a CGUtilCreateBitmapContext. Should I convert them to CIImages? NSImages? From there, what would be faster: An affine transform in the draw method? Or a CIImage transform?

I have no idea what method produces the fastest resizes so any help greatly appreciated.

Didn't Wil Shipley post an article about scaling the icons for Delicious Library? I could easily be imagining things, but I feel like *somebody* posted useful info on this issue once upon a time.
