- Add generic ResourceLocation Index in ShaderIndices.
- Add FogShader and CutoutShader API.
- Implement existing fog/cutout configurations as separate shaders.
- Simplify pipeline shaders to accommodate for new api.
- Separate fog and cutout ubershader components.
- This was much easier than I anticipated, seems we finally have a
usable compiler/shader stitcher.
- Pass fog and cutout IDs to ubershader via a 2x16 packed uint.
- Remove discardPredicate and fogFilter from default material shader.
