      Update the coding tools draft. · ae21d4a4
      Timothy B. Terriberry authored
      Describes an way to use a smaller multiply in the dyadic partition
       function, and removes the description of the non-dyadic partition
       functions, since we don't currently plan to use those, long-term.

      Merging robust and nodesync · cf367854
      Luc Trudeau authored
      The variables robust and nodesync appear to represent the same concept.
      In order to simplify, they are merged into nodesync. This change does
      not alter the bitstream.

      Adds comment to explain nb_coeff in CfL · e3508077
      ltrudeau authored
      Added a comment because nb_coeff is not the number of coefficients in
      the current band, but the number of coefficients in the current band
      plus the number of coefficients in subsequent bands until the end of the
      block.

      Fully order the pvq search candidates · 85433214
      David Michael Barr authored
      For portable and stable sorting, break ties.
      Large differences in output were observed between
      AWCY and an OS X machine because of the platform
      qsort implementation.
