This PR adds a variety of effects to enhance the visual experience.
"soft" clouds look
Tinted shadows
Crude water reflections (sky and sun) and waves
Translucent foliage
Node specular highlights
Adjusted fog color (more saturated where the fog is lighter)
Minor changes to volumetric lighting (crudely simulates the effect of depth)
