  22   - One approach that may be worth investigating is compression (e.g., by PNG).

  50     One approach to solving this would be restricting the candidate set size
  51     for each pixel in the map, so that, e.g., only regions neighboring a local
  52     region (allowing any level of decomposition) can be mapped.
