Detailed Description

template<class PointType_, class TLabel>
class pgl::PolygonSet< PointType_, TLabel >::VertexIterator

Forward iterator flattening every component's rings into one vertex sequence, components in canonical order.

Each component already flattens its own rings, so this pairs a component index with that component's PolygonWithHoles::VertexIterator and rolls over to the next component when the inner iterator runs out.
