The SSA/ASS subtitles can be scaled by the splitter, but that is done by altering
font description in SSA headers. This has exactly the same effect as demuxing the
subs, changing font size in notepad and muxing back. The splitter doesn't even
consider width, height, fullscreen or anything related to rendering, because it
doesn't do any rendering at all.
