1e2656dc88 Use clamp instead of max(0, dot(normalized, normalized)) 
Should help GLSL compiler to optimize them.

18aa119890 Tweak light attenuation. 
Doesnt really change the look of the light but reduce their extent.

c695875654 PointLight: Use a 1/(1 + d + k d^2) attenuation 
This is not physically accurate, but a 1/d^2 attenuation makes light
extend too broad, and went too high if close from the source.

a2d1a86bac Lights: Make possible for gpu drivers to unroll loop. 
GPU doesn't like indirect addressing and thus it's better to have unrolled loop. This is only possible for loop with a static iteration count.

Lower max light level to 16 as it proves sufficient.

34d83859cd Add support for specular light 
Note that specular light is applied unconditionnaly, thus every object will shine.
