      Switch rANS to 15 bit precision, and adjust L_BASE. · 62a94a64
      Alex Converse authored
      This causes rANS to operate at the same precision as the Daala EC.

      ANS: Switch from PDFs to CDFs. · 6bbbe316
      Alex Converse authored
      Make the RANS implementation operate on cumulative distribution
      functions rather than individual probability distribution functions.
      CDFs have shown themselves more flexible to work with.
      
      Reduces decoding memory usage from scaling O(num_distributions *
      symbol_resolution) to O(num_distributions).
      
      No bitstream change. This is an purely implementation change.
