_A_r_g_u_m_e_n_t_s:

     x,y: x and y coordinates of nodes of the voronoi mosaic. Each node
          is a circumcircle center of some triangle from the Delaunay
          triangulation.

    node: logical vector, indicating real nodes of the voronoi mosaic.
          These nodes are the centers of circumcircles of triangles
          with  positive area of the delaunay triangulation.

          If `node[i]'=`FALSE', (`c[i]',`x[i]') belongs to a  triangle
          with area 0.

n1,n2,n3: indices of neighbour nodes. Negative indices indicate dummy
          points as neighbours.

     tri: triangulation object, see `tri'.

    area: area of triangle i. `area[i]'=-1 indicates a removed triangle
          with area 0 at the border of the triangulation.

   ratio: aspect ratio (inscribed radius/circumradius) of triangle i.

dummy.x,dummy.y: x and y coordinates of dummy points. They are used for
          plotting of unbounded tiles.
