* Where `id` is a unique ID to identify this request, `url` is the url of the
* source being pretty printed, `indent` is the number of spaces to indent the
* code by, and `source` is the source text.
*
* On success, the worker responds with a message of the form:
*
* { id, code, mappings }
*
* Where `id` is the same unique ID from the request, `code` is the pretty
* printed source text, and `mappings` is an array or source mappings from the
* pretty printed code back to the ugly source text.
*
* In the case of an error, the worker responds with a message of the form:
*
