Description: Overlay polygon layers by building one constrained
        Delaunay triangulation of every input edge from every layer,
        with crossings inserted as new vertices, and recording which
        input features cover each triangle. The mesh and its index
        answer overlay questions for any number of layers at once:
        where features overlap, how many times, and which features are
        involved. Overlay pieces are dissolved from the mesh, so they
        form an exact partition with shared vertices, unlike pairwise
        polygon clipping. Input is anything the 'wk' package reads, the
        vertex pool comes from 'wkpool' and the triangulation from
        'cdtr'.
