-// Displacement neighbor rules

-// ------------------------------------------------------------------------------------------------ //

-//

-// Each displacement is considered to be in its own space:

-//

-//               NEIGHBOREDGE_TOP

-//

-//                   1 --- 2

-//                   |     |

-// NEIGHBOREDGE_LEFT |     | NEIGHBOREDGE_RIGHT

-//                   |     |

-//                   0 --- 3

-//

-//   			NEIGHBOREDGE_BOTTOM

-//

-//

-// Edge edge of a displacement can have up to two neighbors. If it only has one neighbor

-// and the neighbor fills the edge, then SubNeighbor 0 uses CORNER_TO_CORNER (and SubNeighbor 1

-// is undefined).

-//

-// CORNER_TO_MIDPOINT means that it spans [bottom edge,midpoint] or [left edge,midpoint] depending

-// on which edge you're on.

-//

-// MIDPOINT_TO_CORNER means that it spans [midpoint,top edge] or [midpoint,right edge] depending

-// on which edge you're on.

-//

-// Here's an illustration (where C2M=CORNER_TO_MIDPOINT and M2C=MIDPOINT_TO_CORNER
