If there are no side effects caused by get_section() and put_section()
this (not very elegant) extension to vil_load can solve the problem of
changing components and flipping rows:

vil_image vil_load(char const* filename)
{
  vil_image i =3D vil_load_raw(filename);
  bool top_first, bgr;
  if (   i.get_property(vil_property_top_row_first, &top_first) && !top_f=
irst
     &&  i.components() =3D=3D 3 && i.get_property(vil_property_component=
_order_is_BGR,&bgr) && bgr) {
      i =3D vil_flipud(i);
      i =3D vil_flip_components(i);
  }
  else {
    if (i.get_property(vil_property_top_row_first, &top_first) && !top_fi=
rst)
      i =3D vil_flipud(i);
    if (i.components() =3D=3D 3 && i.get_property(vil_property_component_=
order_is_BGR,&bgr) && bgr)
      i =3D vil_flip_components(i);
  }
  return i;
}
