docs: Replies if the specified point (<var>x</var>,<var>y</var>)
  was inside the figure of this MapElement.
  
  <p>If this MapElement has no associated figure, this method
  always returns <code>false</code>.
  
  @param point is a geo-referenced coordinate
  @param delta is the geo-referenced distance that corresponds to a approximation
  distance in the screen coordinate system
  @return <code>true</code> if this MapElement had an associated figure and
  the specified point was inside this bounds of this figure, otherwhise
  <code>false</code>
