In the current implementation, only the image request handler is able to provide scaled previews, while the previews rest endpoint is able to do this for other resources as well.
Unfortunately, the endpoint is protected and cannot be used for users that are not logged in, thereby making it impossible to provide previews for other resources such as movies or files on public facing pages.
