title: Boost Library and closest points
body: <p>I can find the distance between a point <code>MyPoint</code> and a polygon <code>MyPolygon</code> with </p>
  
  <pre><code>double dist = boost::geometry::distance(MyPoint, MyPolygon)
  </code></pre>
  
  <p>obviously the actual closest point on <code>MyPolygon</code> has to be computed somewhere. Is there an easy way to get that closest point? I can't find anything in the Boost Documentation and I'm sure others had that problem too.</p>
