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.

It should improve performance a lot, but it handles at most 32 simultaneous lights on screen.

This allows to bypass alpha test, and have colored specular lights.

The attenuation assumes a power distributed on the whole sphere surface.

Note that specular light is applied unconditionnaly, thus every object will shine.
TODO : Specular map should be defined using texture or a material flag.
