This reflects the fact that this filter now renders all types of subtitles, not just ASS subtitles. Always compile this filter, not just on CONFIG_ASS. Note that --no-ass still disables auto-inserting this filter. It's the only way to disable auto-insertion, so keep it even though it's not really ASS specific anymore. --no-ass also disables using libass for rendering text subs directly.
