If I've already calculated the lighting, why would I want the browser to
do any lighting at all? You can manage to avoid all lighting in the
current spec (by using only ambient or emissive colors) but it's not
pretty. This is why I'd like to see a LightModel node in 1.1 that would
at least allow me to turn off all lighting by the browser. I could then
leave my colors in the diffuseColor fields and rendering may even be
faster.
I think the lighting equations should remain an implementation detail.
The ability to turn off lighting may help make this more acceptable.
