a6293b9861 Initial refactoring on shader usage and generation 
`IShaderSource` was designed with the idea that if you want a shader,
you must want it for a node. So it depends heavily on being given a tile
material and the node drawtype. But this doesn't make sense neither in theory
nor in practice.
This commit takes a small step towards removing the incorrect abstraction.

Visual Effects Vol. 1 (#14610) 
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)
