Yeah, that's probably a good second step. This step doesn't change the
existing parameter format, it just extends it :-) That'd be a good thing
to consider when av_set_options_string() is fully merged, though.

Perhaps it'd be a bonus, but I don't feel it's necessary at the moment,
since this is so much more expressive (in addition to aligning to the
other edges, it also makes centering easy, etc.). At least not necessary
for this first patch. :-)
