    m42238/geometry: neighbour contextualised coding of occupancy · ca4ac3f9
    David Flynn authored
    This commit provides an implementation of m42238 to code occupancy:
     - a node's child occupancy is contextualised based on the adjacent
       neighbours of the parent node.
     - when an isolated node is occupied by only a single child, the
       sub-node address [0,7] is directly coded instead of the 8-bit
       occupancy word.
     - collection of neighbour occupancy is performed using a scatter/
       gather operation upon the insertion of each child node into the
       fifo queue.
     - the feature may be controlled via the command line / config file
       using the --neighbourContextualisation=1|0 option
