    At the edges of the picture only a subset of partitions are legal. Add
    new contexts for these borders so they don't distort the probabilities of
    the interior of the image where all partitions are legal.
    
    Only include one context for each block size of each border direction
    because so few blocks fall into these contexts to begin with.
