why not add a new (6th) option to expand, so someone could do things
like:
-vf expand=:600:::4/3  to get the video expanded to 600 height, and
the width calculated from the given 4:3 aspect ratio.
also if someone only wants aspect set, do -vf expand=aspect=4/3
(it's handled by subconfig parser, equal to expand=:::::4/3)

it's ugly, and wont work in g2 or any future version supporting dynamic
plugin loading.
