I've seen in this comment that half_size is lossless for bayer cameras.
Does that mean that the default demosaicing algorithm (LGPL licenced) in libRaw is as simple as what half_size does (regrouping pixels by groups of 4)?
Or does dcraw_process() use a more evolved algorithm? If yes, what is this algorithm? DCB?
