Hello Marco !
I believe the highest level (say - level N) contains only vertices. These
vertices lie on edges of triangles at level (N-1). pfASD doesn't display
these vertices but uses them to match neighboring triangles at level (N-1).
Two triangles of level (N-1) are considered neighbors if they share a reference
vertex (pfTerrainFace::refvert) on one of their edges.
