This patch adds the nextsub filter, (a replacement for extsub). It
allows better control over which subtitle indexes can be used, better
positioning control, allows opacity, zooming, rgb colours, etc. It's
well documented (something extsub was in need of). This is an old patch
but I see it still didn't make it in, so I'm resubmitting it.
YES yes, I know. I need to determine these subtitle indices from
the VOB header and make them available to dvdrip. Been on my todo list
for two years now. That, and the "forced" flag. What can I say.
