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.

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.
