We then group the\n # rows into _Encoding objects, by their "characteristic" bitmap.\n # The characteristic bitmap is a binary number representing how\n # many bytes each column of the data takes up to encode. Each\n # column is encoded in four bits. For example, if a column has\n # only values in the range -128..127, it would only have a single\n # bit set in the characteristic bitmap for that column. If it has\n # values in the range -32768..32767, it would have two bits set.\n # The number of ones in the characteristic bitmap is the "width"\n # of the encoding.\n #\n # Each encoding as such has a number of "active" (ie. non-zero)\n # columns. The overhead of encoding the characteristic bitmap\n # is 10 bytes, plus 2 bytes per active column.\n #\n # When an encoding is merged into another one, if the characteristic\n # of the old encoding is a subset of the new one, then the overhead\n # of the old encoding is completely eliminated. However, each row\n # now would require more bytes to encode, to the tune of one byte\n # per characteristic bit that is active in the new encoding but not\n # in the old one.\n #\n # The "gain" of merging two encodings is how many bytes we save by doing so.\n #\n # High-level algorithm:\n #\n # - Each encoding has a minimal way to encode it. However, because\n # of the overhead of encoding the characteristic bitmap, it may\n # be beneficial to merge two encodings together, if there is\n # gain in doing so. As such, we need to search for the best\n # such successive merges.\n #\n # Algorithm:\n #\n # - Put all encodings into a "todo" list.\n #\n # - Sort todo list (for stability) by width_sort_key(), which is a tuple\n # of the following items:\n # * The "width" of the encoding.\n # * The characteristic bitmap of the encoding, with higher-numbered\n # columns compared first.\n #\n # - Make a priority-queue of the gain from combining each two\n # encodings in the todo list. The priority queue is sorted by\n # decreasing gain. Only positive gains are included.\n #\n # - While priority queue is not empty:\n # - Pop the first item from the priority queue,\n # - Merge the two encodings it represents,\n # - Remove the two encodings from the todo list,\n # - Insert positive gains from combining the new encoding with\n # all existing todo list items into the priority queue,\n # - If a todo list item with the same characteristic bitmap as\n # the new encoding exists, remove it from the todo list and\n # merge it into the new encoding.\n # - Insert the new encoding into the todo list,\n #\n # - Encode all remaining items in the todo list.\n #\n # The output is then sorted for stability, in the following way:\n # - The VarRegionList of the input is kept intact.\n # - The VarData is sorted by the same width_sort_key() used at the beginning.\n # - Within each VarData, the items are sorted as vectors of numbers.\n #\n # Finally, each VarData is optimized to remove the empty columns and\n # reorder columns as needed.\n\n # TODO\n # Check that no two VarRegions are the same;
