	Poorly stated but not easy to make scientifically correct
generalities. The 1 and 10 should have been +infinity for most I
have played with. From memory phong (not phong_size) says not
much difference over 5 which is quite a way from +infinity. But
even phong_size at 70 or 70000 is a long way from infinity. And
0-70 ia about the noticeable range of effect. 

	I presume readers familiar with evaluating equations know what I
am talking about. Can any of you help me explain? 

	A FAQ file of "these ranges produce the differences" would be
useful.
