Comment (by Aymeric Augustin):
In fact using `django.template.Engine` in standalone mode already works:
{{{
>>> from django.template import Context, Engine
>>> engine = Engine()
>>> template = engine.from_string("Hello {{ name }}!")
>>> context = Context({'name': "world"})
>>> template.render(context)
'Hello world!'
}}}
`DjangoTemplates` is a thin integration layer for configuring an `Engine`
according to the project settings. It doesn't make sense to remove its
dependencies on settings. Just use `Engine` directly.
The documentation explains the roles of these classes without ambiguity
and specifically mentions using the template engine outside of a Django
project (meaning without Django settings):
https://docs.djangoproject.com/en/1.10/topics/templates/#engine
> django.template.Engine encapsulates an instance of the Django template
system. The main reason for instantiating an Engine directly is to use the
Django template language outside of a Django project.
> django.template.backends.django.DjangoTemplates is a thin wrapper
adapting django.template.Engine to Django’s template backend API.
For these reasons, I don't see what needs to be done here.
