Don't use margins for events that should not be overridden

libass already does not use the margins for events using \pos. This is
not quite complete: there are other tags that we consider as "not
dialogue", and which should not be overridden. These tags do not use
EVENT_POSITIONED, and thus use the margins, which can mess up rendering.
