Revision 105a1d8 by Clément Fukhaut (pbr-viewport)
May 6, 2016, 13:55 (GMT)
Huge codebase changes :
- Made ssfx "module" to manage screen space effects applied at material stage
- Moved probe functions to their own module
- Divided Shading glsl file into bits that are gathered when making glsl_material_library making files shorter and more organized
- Moved function generating luts and random texture to gpu_luts.c that will contains all textures needed to acheive some effects.
- GPU_PBR in GPUBuiltin is just a placeholder to trigger the uniform binding

Optimisation / correction :
- GLSL : Number of bsdf sample is now passed via an uniform instead of a #define. This means changing quality settings will no longer recompute every shaders in the scene. But this has a small perf cost.
- GLSL : Hammersley numbers are precalculated and stored inside a texture. This may have a performance impact and I will change it to a static table.
- GLSL : Random per pixel numbers are done using a texture like SSAO.
- GLSL : Lots of parameters (only for pbr) are now defined as uniform and passed at binding stage (this minimize the use of GPU_builtin).
- GLSL : most variables used in sampling algorythm are defined as global variables.
- Bsdf sampling is now using the real algorithm and not the split sum approximation (which was unecessary).

Features :
- Added toon shader support (only point light support).
- Added holdout.
