	To be more precise, in real life, highlights are caused by blurred
reflection of the light-emitting object. Since light-sources (even
area lights) are single points, no amount of reflection blurred or
not would show them. Hence, the phong and specular keywords that
intend to fake this effect.

	When you use a radiosity light emitting object, this object is
large enough and bright enough that you can do the physically
accurate thing: add a slight amount of blurred reflection to your
object and the highlight should appear.
