The demosaicing operation implemented in GEGL is the nearest neighbour
equivalenet of demosicing, thus not really suitable for real work. It
is alos highly doubtful that you want to (bayer) demosaic something
coming from a scanner, since
there isn't a good reason for the scanner to provide a bayer pattern
in the first place.
