This seems fine. I think you could have left this in the raw_codec target, but I
don't think this is a problem. (It just means that SK_CODEC_DECODES_RAW is
defined in targets that never know it or need to know it.)

Sure thing, I moved this back to the codec.gyp. We only need this in that very
special target.
