    Decide which hash-table corpus samples go into by a 4bit per pixel start
    fragment, when computing a relevant subsetting index for which hashtable to use
    - include neighbouring "bins" per pixel in neighborhood, as well as full
    variation for that part of index if needle contains transparency.
    
    The result is a quality near exhaustive search; at orders of magnitude better
    performance.
