      [CFL] Better encapsulation · 3dc55e0f
      Luc Trudeau authored
      The function cfl_compute_parameters is added and contains the logic
      related to building the CfL context parameters. As such, many cfl
      functions can now be encapsulated inside of cfl.c and not exposed to the
      rest of AV1.
      
      This also allows for supplemental asserts that validate that the CfL
      context is properly built.

      [CFL] Compute Luma Average Over Partition Unit · 3e18e4ae
      Luc Trudeau authored
      Extract the compution of the luma reconstructed average out of cfl_load
      and into cfl_compute_average. The reconstructed luma average is stored
      in the CFL_CONTEXT to avoid computing it for each transform block and
      for each plane.

      [CFL] Change cfl_load to use width and height · 30596fb2
      Luc Trudeau authored
      Since the size used with cfl_load can either be based on the transform
      block size and the prediction block size, width and height are used as
      parameters instead of TX_SIZE.
      
      This resolves a problem where cfl_compute_alpha_ind was reading
      uninitialized memory.

      [CFL] Alpha signaling · f533400a
      Luc Trudeau authored
      Writes and reads alpha to and from the bitstream.
      
      A special case is needed on the encoder side to handle prediction block
      skips. Since whether or not a prediction block is skipped during CfL, a
      rollback is required if the block was skipped and the alpha index was
      not zero. The advantage of this is that no signaling is required when
      the prediction block is skipped as it is assumed tha the alpha index is
      zero.
      
      A encode facade is added to the intra prediction facade as CfL requires
      special encoder side operations.

      [CFL] Store luma as prediction for chroma · e3980281
      Luc Trudeau authored
      Stores the reconstructed luma pixels for each transform block inside a
      prediction block. Rectangular transform blocks are supported.
      
      As for RDO, after all the modes have been tested for luma, an extra
      encoding is perform in order to store the reconstructed pixel values of
      the best mode. These values are then used for RDO on the chromatic
      planes.

      [CFL] Custom block-level DC_PRED · f8164157
      Luc Trudeau authored
      Adds the CfL experiment flag and computes a block-level DC_PRED that is
      required by CfL in order to compute alpha_cb and alpha_cr.
      
      The rate-distorsion impact of computing DC_PRED at the prediction block level
      for chroma planes is rather small
