inherited

Insert a vertex into the vertex set.

Create an entry in the vertices lookup and optionally inserts the newly created vertex into an existing linked list.

Parameters

aIndex	the index of the vertex
pt	the point to insert
last	the last vertex in the list
aUserData	user data to associate with the vertex

Check whether the segment from vertex a -> vertex b is inside the polygon around the immediate area of vertex a.

We don't define the exact area over which the segment is inside but it is guaranteed to be inside the polygon immediately adjacent to vertex a.

Returns: true if the segment from a->b is inside a's polygon next to vertex a.
