Tessellate a polygon into triangles.
Called when a tessellation shape begins. Stores the shape type for later reference.
Called when tessellation must create a new point. Ideally this is where user data would be merged into a new point, but since we don’t support user data, there’s nothing to do but create the point and return =].
Called with tessellation finishes with a shape. Saves all relevant data and sets up for another shape to come its way.
Error!!!!
Called when tessellation sends us a vertex. Uses the current shape type to figure out how the vertex will be processed/stored.
Get the global winding rule for the keyword passed in.
Determine if the points of a polygon are in clockwise order.
