NAME
     load_vsites(), find_vregions() - subroutine package to  com-
     pute Voronoi regions of sites in the plane

SYNOPSIS
     #include voronoi.h

     int
     load_vsites (n, sites, uxmin, uymin, uxmax, uymax)
     int n;
     float sites[][2];   /* [][0] is x, [][1] is y */
     float uxmin, uymin, uxmax, uymax;

     /* load_vsites():
         accept the n voronoi sites (x_k, y_k)  0 <= k < n
         calculate and store the voronoi diagram over the n sites,
         clipping all infinite edges to user's bounding box:
          [uxmin <= x <= uxmax; uymin <= y <= uymax].

         note: if (uxmin,uymin,uxmax,uymax are all == 0.0), OR
          if these do not enclose the data, load_vsites()
          will compute a correct bounding box over the input.

         returns:
          -1 if error
           0 otherwise
     */
