Add a Miniview to the Surface with the given id. If the Surface already exists and has been initialised the Miniview
will be added immediately; otherwise it will be enqueued for later processing. This method is not typically something
a user of the Toolkit will need to call, as the Miniview component does this internally. But if you find that you want
to register a miniview programmatically after your UI has been initialized, this method is what you need.
