The problem is that we render the subtitles _before_ the scaling up at
playback time, and we have no idea about what size (or more importantly)
aspect will it be scaled to. Of course the information is available
somewhere in mplayer's dataspace, but the vobsub rendering module is
obviously not aware of it.

Can someone quickly pinpoint me the right place to fetch this
information from? (I can look for it, and eventually I will fint it
without help, but a quick tip would make it less painful...)

Probably the same thing here: the aspect ratio if the comint scale-up is
unknown by the sub rendering module. If I can find the solution for the
SPU module, I will also adopt it to the SUB module.
