Rudolf Polzer 633fde4ae5 sd_lavc, sd_spu: make dvdsub stretching conditional on --stretch-dvd-subs.
We found that the stretching - although it usually improves the looks of
the fonts - is incorrect.

On DVD, subtitles can cover the full area of the picture, and they have
the same pixel aspect as the movie itself.

Too bad many commercially released DVDs use bitmap fonts made with the
wrong pixel aspect (i.e. assuming 1:1) - --stretch-dvd-subs will make
these more pretty then.
