test case


In test case, a polygon is drawn with lighting parameters set in such a way
that most   values drop out and the resulting pixel color is a function  of the
normal vector.

The equation reduces to c = max(0, n dot VP)  and (n dot VP) reduces to
cos(theta). 

 Local light sources use the unit length vectors but have a w value of 1.0E-6. 
Using the w value makes the local light so distant that it is an infinite light
for all practical purposes.
