Well, since Nautilus already depends on libexif12 and libexempi, those
would be the obvious candidates.

That way GCM won't pull in extra dependancies...

doesn't support half of the fileformats dcraw does... Again, I haven't
checked it recently so I could be mistaken!

Maybe LibRaw is a workable solution?
