An article arguing in favor of Schlick's approximation in RGB renderers

[Un Flic]

Hello guys and gals,

Decided that this could be interesting for you, especially for those like me who are too lazy to type big formulas in code. The article says that the Fresnel equations are not that good approximation in RGB and Schlick's with  Lazanyi's correction is better choice.
