static get type() {

		return 'RendererReferenceNode';

	}
This node is a special type of reference node which is intended
for linking renderer properties with node values.
```js
const exposureNode = rendererReference( 'toneMappingExposure', 'float', renderer );
```
When changing `renderer.toneMappingExposure`, the node value of `exposureNode` will
automatically be updated.
