/**
 * LitMaterial comprises a shader chunk implementing the material "front end" (the shader program
 * providing the material surface properties like diffuse, opacity, normals etc) and a set of
 * flags which control the material "back end" (the shader program calculating the lighting,
 * shadows, reflections, fogging etc).
 *
 * The front end and back end together form a complete PBR shader.
