static int gray_raster_render(....)
{
  const QT_FT_Outline* outline =
    (const QT_FT_Outline*)params->source;

  ....

  /* return immediately if the outline is empty */
  if ( outline->n_points == 0 || outline->n_contours <= 0 )
    return 0;

  if ( !outline || !outline->contours || !outline->points )
    return ErrRaster_Invalid_Outline;
