      public static org.locationtech.jts.geom.Geometry insertPoint(org.locationtech.jts.geom.Geometry geometry, org.locationtech.jts.geom.Point point, double tolerance) throws SQLException
      Returns a new geometry based on an existing one, with a specific point as a new vertex.
      Parameters:
      geometry -
      point -
      tolerance -
      Returns:
      Null if the vertex cannot be inserted
      Throws:
      SQLException - If the vertex can be inserted but it makes the geometry to be in an invalid shape
