    Fix a bug in the DAALA_TX 16-point DST functions. · 69a16433
    Nathan E. Egge authored
    The OD_FDST_16() and OD_IDST_16() macros were written for use in the
     OD_FDCT_32_ASYM macro which took asymmetrically scaled input and
     after running an asymmetric butterfly step, passed it through to
     the 16-point Type-II DCT and 16-point Type-IV DST.
    Because the DST implementations were never tested as stand alone
     transforms, some of the signs from the butterfly step ended up inside
     the DST macros.
    These extra operations will be addressed in a follow up patch.
