I'll make tests at home...

I don't comment my tests in general...I know, it's not a good thing...
The advantage of the shader is that the lights positions are given (not
exactly but, the result is the same, you know where it comes from) and ease a
lot the work...this shader is simple (I think) because, there is no real
physic behind !
I just do a gradient with the 2 colors. the coef is given by the angle between
the light and the surface normal (Ln.Nn).
