    Fix bug with chroma-sub8x8 + resizing · 11132ce3
    David Barker authored
    The special path in build_inter_predictors for chroma blocks
    corresponding to sub8x8 luma blocks would always fetch the
    scale factors from 'xd', which correspond (at least in the
    decoder) to the references of the block for which is_chroma_reference
    returns true.
    
    The correct behaviour is to fetch the scale factors from 'ref_buf',
    which corresponds to the references of the block currently being
    predicted.
    
    This patch fixes some encode/decode mismatches which were caused
    by the above behaviour when the various reference frames had
    different sizes.
