I would prefer a global option (which is why the code was dropped during the 
port). There is actually already an option that does part of that 
(--spumargin) so it might be worth basing your code on that.

As for the aspect-ratio this should be relatively easy to fix since the 
subpicture core supports rescaling, I'll have a look at it.
