Since these need to be refcounted, we throw them directly into struct
mp_image instead of being part of mp_colorspace. Even though they would
semantically make more sense in mp_colorspace, having them there is
really awkward because mp_colorspace is passed around and stored a lot,
and this way their lifetime is exactly tied to the lifetime of the
mp_image associated with it.
