I am not sure this is necessary, but it can not hurt. I'll add such a
comment if everyone is fine with it.

Actually, this is similar but not identical, since ASS actually encodes the
canvas resolution in the header (and we should maybe consider exposing it in
the codec context), but completely messed up the handling of pixel aspect

Currently not (but lavfi does not handle them yet anyway). With a proper
support for subtitles filters, I think it will be possible to make things
