    tscc2: do not add/subtract 128 bias during DCT · 4cfb0d87

    It turns out that the reference decoder subtracts 128 from DC during block
    decode but adds it back during reordering block with zigzag pattern.
    Transforming block with incorrect DC caused heavy visual artifacts for
    many quantisers.
