Porting to GraphicsMagick ought to be fairly straightforward.

Copy pasting a textbook image scaler into the emacs codebase ought also
be straightforward.

If this is done I would humbly suggest that the
ImageMagic/GraphicsMagick code is kept around as an alternative.

This is because Imagemagic has support for some less common file formats
that I use. I can of course keep a patch around or make a module.

As an aside I used the ImageMagick code in Emacs to preview about 130000
images that I scanned using Emacs. I remember it as being very
stable. But I guess times change.
