By the time we create the context the swapchain and surfaces aren't fully constructed. However, we luckily call SetContainer on the initial surface before we call create_context, so it should work for now.

(Incidentally, we create the context with the front buffer as target, so context_acquire with the back buffer as target should set context->render_offscreen correctly anyway. For some reason though it doesn't (Or did not, when I wrote the render-to-fbo code. Or maybe that was after a Reset() call)
