I like the idea, however I wonder do we really need 3 new global
variables to do that?

afaik by design config() could be called multiple times without
calling uninit(), so this functionality could be entirely internal for
the vo. Of course this is used only with -fixed-vo, that btw should
already be enabled by default... ;)
