/**
 * This renderer doesn't format the output itself, but rather allows multiple
 * renderers to be easily called, which will render the content in sequence.
 *
 * Pass the renderers you wish to chain together as elements in an array to
 * this function. Important - you should pass the renderer as if you were
 * going to give it to the `render` property directly (i.e. if it is just a
 * simple function, don't execute it).
