That's not what I meant to say, I was only trying to say that unless you are
converting to (or from) a bitmap format or display subtitles,
AVSubtitleRect should never be involved because its assumption of any
kind of a (single, fixed) coordinate system makes it unsuitable for anything else.
A corollary to this was that thus subtitle decoders should not be used
for anything that does not create (pure) bitmap subtitles.
