docs: Load a template from the loader.  If a loader is configured this
          method asks the loader for the template and returns a :class:`Template`.
          If the `parent` parameter is not `None`, :meth:`join_path` is called
          to get the real template name before loading.
  
          The `globals` parameter can be used to provide template wide globals.
          These variables are available in the context at render time.
  
          If the template does not exist a :exc:`TemplateNotFound` exception is
          raised.

             If `name` is a :class:`Template` object it is returned from the
             function unchanged.
