  28. The following program draws some triangle strips with reflectange equation
  29. setting = PREFL_AMBIENT.  It is expected that the triangle strips be rendered
  30. with the current interior colour since the current light source state is empty
  31. This program originated from a bug report created by the InsPEX test group.
