// An AugmentMaterial pass over a CustomMaterial.
//
// The augmentation is folded into the custom material's shader path key, and
// that key is also emitted as the "//Shader name -" comment of the generated
// shader. An augment shader is always more than one line long -- the license
// header alone sees to that -- so appending it to the key verbatim used to
// push everything after its first line out of the comment and into the shader
// as stray code, which then failed to compile.
//
// The material paints itself red and the augment shader overrides that with
// green, so a sphere that is not green means the augmentation never ran.
