hmm. not a bad idea :)
and really easy and clean to implement.

this one is a bit harder. maybe, after vo->check_events call in mplayer.c,
we could check for changes and tell it to the vf filters.
anyway asking the vo w/h for every frame is simpler, and won't eat so much
cpu to worth to optimize.

of course no
it's required only for auto-inserted ones, currently: scale, expand, pp
