ronoi diagram edges and vertices, thus giving
enough information to construct the Voronoi diagram of a set of points
and linear segments. The requirements for the input/output
coordinate type of
the builder geometries are not the same as for the rest of the
Boost.Polygon library. The main differences are in the following:<br>
      <ul>
        <li>The input coordinate type is not required to be integral (while it
still should be an integer type)</li>
        <li>The output coordinate type (for
