      EC_ADAPT: Perform backwards updates directly on CDFs. · 028b57f5
      Thomas Davies authored
      The initial CDF for each frame is stored in
      the frame context. CDFs for actual coding are
      stored in the tile structures, and these are
      what get adapted. The initial CDF is replaced
      by an average CDF derived from these tile CDFs.
      This is carried forward to future frames when
      backward adaptation is on.
      
      CDFs are no longer set from the 8 bit probabilities
      in backwards adaptation.
      
      For now, 8 bit probabilities are maintained for
      use in the encoder and for symbols which do not
      have a CDF.
