    gegl: use RGBA rather than RaGaBaA for mipmap related scaling
    
    This will cause some minor color-of-transparent-pixels-fringe leaking,
    but paths from commonly used raster storage/layer formats are likely
    nearer to RGBA float than RaGaBaA float, thus being able to use cheaper
    conversions.
    
    The linear already existing versions do not enforce use of
    pre-multiplied alpha either.
