make_edit_distance - use MASKED_DOTS since it does not have a simple relationship to the HEADER_BITS/BODY_BITS for HGR - try disabling transposition distances for Damerau-Levenshtein, this may give better quality screen - introduce separate notion of MASKED_DOTS which is the number of (coloured) pixels we can extract from MASKED_BITS. For HGR this is not the same. - fix bug in _fix_array_neighbours that was not fixing headers for HGR - don't cache everything in byte_pair_differences, it's effectively unbounded. Using 1M for LRU size seems to work just as well in practise, without leaking memory. - fix bug in _diff_weights when comparing content, we want to evaluate the effect of storing content byte in each offset separately, not cumulatively. - add a consistency check function (not currently wired up) to assert that headers/footers are in sync across columns - HGR should have 16 body bits, this was causing headers not to propagate correctly to/from neighbouring column - add test case for this bug video - Use 8 random bits consistently, using 16 in some places may have introduced bias - ignore palette bit when comparing 0x00 and 0x7f in sanity check
