+/// # Approximate an half-edge

+/// The approximation of an half-edge is the approximation of its curve within
+/// the boundary defined by the half-edge's start and end vertices, plus the
+/// position of the start vertex.
+///
+/// By including the start vertex and not the end vertex, a whole chain of
+/// half-edges can be approximated by simply appending the approximations of
+/// each half-edge, without the necessity of any deduplication of points.
