   * \brief
   *
   * ParametricSpaceToImageSpaceMeshFilter takes an itk::Mesh on which
   * the point Data is expected to contain itk::Index of itk::Image pixels
   * associated with each point of the Mesh, and construct with them a new
   * mesh whose points are in the coordinates of those pixels.
   *
   * The input mesh is assumed to represent pixels in some parametric space.
   * The output mesh is suitable to be superimposed as an overlay to the
   * associated image.
   * by the user.
   *
   * The additional content of the mesh is passed untouched. Including the
   * connectivity and the additional information contained on cells and points.
   *
   * \warning This filter also assumes that the Output Mesh has as type
   * for the PointDataType the PointType of the input mesh.
