      Make the quantizer exact. · e04e2935
      Timothy B. Terriberry authored
      This replaces the approximate division-by-multiplication in the
       quantizer with an exact one that costs just one add and one
       shift extra.
      The asm versions have not been updated in this patch, and thus
       have been disabled, since the new method requires different
       multipliers which are not compatible with the old method.

      Redo the forward 4x4 dct · d0dd01b8
      Yaowu Xu authored
      The new fdct lowers the round trip sum squared error for a
      4x4 block ~0.12. or ~0.008/pixel. For reference, the old
      matrix multiply version has average round trip error 1.46
      for a 4x4 block.
      
      Thanks to "derf" for his suggestions and references.

      cosmetics: trim trailing whitespace · 94c52e4d
      John Koleszar authored
      When the license headers were updated, they accidentally contained
      trailing whitespace, so unfortunately we have to touch all the files
      again.
