Hello.

Nothing useful came to my mind, how to distinguish between whether
specifying expanded image resolution or aspect of the expanded window,
so I have created new filter. If someone gives me a clue, how to do this
without breaking curent -vf expand=w:h:x:y:o syntax, I will gladly alter
vf_expand.c directly to add this feature (IMHO it is better solution).


Best regards
