  /*****************************************************************************
   * cap_pssetincr
   *
   * Assigns the 'step increment' to be used when dividing up the line segments 
   * around a reference when looking for places to position an object outside
   * the reference.
   * Note, if a value isn't assigned, then 5% of the smallest dimension of the
   * area will be used.
   * Note that the value should be in terms of the same cartesian coordinate 
   * system as the vertexes for the objects, not earth coordinates.
   *
   * Input parameters:
   *  placements      PlacementSet    handle to PlacementSet 
   *  increment       float           increment value
   *
   * Output parameters:
   *  *iret       int             Return code
   *                                  0 = Function successful
   *                                 -1 = Invalid object
