This changes the bent normal effect to be a bit more subtle. I also tuned down the bent normal blending factor so mesh faceted look may appear more in occluded regions. this is to increase the fidelity of the indirect lighting. This blending might be a parameter in the future. Based the calculation on "Bent Normals and Cones in Screen-space" by O. Klehm, T. Ritschel, E. Eisemann, H.-P. Seidel
