What do you think about adding a new control call that gets the screen
size? The vo driver would probably need to notify the filters about
screen size changes somehow too...

Btw You have said that filters shouldn't do anything (be transparent)
if they don't get any parameters a few times now. I agree with you
that this is desirable for filters that might be automatically
inserted. But is there any reason for other filters such as a
hypothetical '-vop add_black_bands_with_subtitles' to be transparent?
