- AtmosphericScatteringXXX files where definition/editor and shader code of the fog functions are and that are used by any shader where fog is needed (full pass opaque fog, transparent forward materials...)
- Implemented basic linear/exponential fog with Uncharted 4 "Mip Sky" color fetch trick.
- Merged PerFrame/PerView into UnityGlobal
- Merged most sub systems constant buffers into UnityGlobal (decal, subsurface, lighting, ...)
- Moved AtmosphericScattering into the Lighting folder.
