      This experiment has been adopted, we can simplify the code
      by dropping the associated preprocessor conditionals.

      Mark AOM_QM matricies const. · 90243cf9
      Ralph Giles authored
      These large (200 KB) static stables are functionally read-only. Marking
      them const moves them to the read-only section of shared libraries,
      reducing memory footprint when multiple application processes are
      running simultaneously.

      Turn on ref-adapt by default · 7736239d
      Zoe Liu authored
      This experiment of ref-adapt removes the option of COMPOUND_REFERENCE
      from the frame level reference_mode setup, and hence removes 1 bit
      in the frame header syntax. It now allows only SINGLE_REFERENCE or
      REFERENCE_MODE_SELECT to specify in the frame header.
      
      No noticeable coding performance impact has been observed.

      Turn on frame_sign_bias by default. · d4f22f45
      Zoe Liu authored
      This experiment of frame_sign_bias is to remove the 7 bits in the
      frame header that signal the sign bias value for the 7 reference
      frames. Instead of explicit signaling, this experiment is to use
      the frame_offset value to derive the frame sign bias. It achieves
      -0.08~-0.1% coding gain on average. It has been adopted by AOM.
