Detailed Description
A line segment (edge) shape. These can be connected in chains or loops to other edge shapes. Edges created independently are two-sided and do no provide smooth movement across junctions.

Set this as a part of a sequence. Vertex v0 precedes the edge and vertex v3 follows. These extra vertices are used to provide smooth movement across junctions. This also makes the collision one-sided. The edge normal points to the right looking from v1 to v2.
