      Encode and decode multiple tile groups. · ce12003d
      Thomas Davies authored
      A tile group is a set of tiles in scan order.
      Each tile group has a version of uncompressed and compressed headers,
      identical apart from tile group parameters.
      Encoding probability updates takes account of the number of
      headers to control overheads.
      The decoder supports arbitrary numbers of tile groups with
      arbitrary number of tiles. The number of tiles in a TG is
      signalled in the uncompressed header for that TG.
      The encoder currently only supports a fixed number
      of TGs (3, when error resilient mode is on) of equal size
      (except possibly for the last one).
      The average BDR performnce with 3 tile groups versus
      anchor with error resilient mode and up to 16 tiles is:
      NR YCbCr:      3.02%      3.04%      3.05%
      PSNRHVS:      3.09%
      SSIM:      3.06%
      MSSSIM:      3.05%
      CIEDE2000:      3.04%

      Work around to avoid mismtach on adaptive scan experiment · d58f39d5
      Angie Chiang authored
      1) Turn off SIMD quantizer in adapt_scan experiment because the iscan is
      not 16-byte aligned now.
      2) Turn off eob-specific dqcoeff initialization in
      inverse_transform_block_inter and inverse_transform_block_intra
      3) Turn off transform optimization for special eob because it is not
      compatible with adapt_scan experiment
