     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 indi-
          cate 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.
