Support three.js partial shader chunks

[hsimpson]

When using the ShaderMaterial from three.js then there are some things injected into vertex and fragment shaders (some shader chunks).

This is also the case when using a custom A-Frame shader.

Built-in uniforms and attributes: https://threejs.org/docs/index.html#api/en/renderers/webgl/WebGLProgram

Unfortunately not, sorry. This is a spare time project and at the moment I have so many tasks in my full time job ;-)
