    Preliminary code for variance based paritioning · e39ecfaa
    Deb Mukherjee authored
    Brings back most of Jim's previous patch for choosing
    partitioning based on variance while making it compatible
    with the current state of the code. Also adds a
    nonrd_use_partition() function to recursively encode  for any
    arbitrary sb_type decisions within a 64x64 block; and
    includes some refactoring.
    Currently, when the VAR_BASED_PARTITIONING mode is turned on
    for speed 7, there is a 10+% speed-up observed.
    Experiments/improvements with this new partitioning method
    will be conducted subsequently.
