Port of subsurface scattering from the eevee-rewrite branch to EEVEE Next.
https://projects.blender.org/fclem/blender/src/branch/eevee-rewrite

Other changes:

  • Fix gbuffer normal and ior packing.
  • Write the material eClosureBits to the gbuffer stencil.

Known Issues:

  • SSS Transmittance energy is greater than Cycles with the same settings.

This subsurface pass should go inside SubsurfaceModule.

Note that, currently, the subsurface algorithm is quite simple, we might extend it in the future. Making everything in one place will avoid much trouble later on.

You can init the pass in all cases and only submit it if the closure bit is present.
