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.

30a030bd4c Light: Pseudo sort lights distance using bucket to evict them fast.
Lower max light level to 16 as it proves sufficient.

4d0b9236b2 Lights: improve bandwidth usage
It should improve performance a lot, but it handles at most 32 simultaneous lights on screen.

65b32757f3 Separate Diffuse and Specular components
This allows to bypass alpha test, and have colored specular lights.

88ac0ba6cf Attempt to mimic blender light behavior.
The attenuation assumes a power distributed on the whole sphere surface.

34d83859cd Add support for specular light
Note that specular light is applied unconditionnaly, thus every object will shine.
TODO : Specular map should be defined using texture or a material flag.
