For a given subtitle language you can now chose to display
only the forced subtitles. Defaut is set to "show all subtitles"
so that current mplayer behaviour is not changed.
For DVD:
Use -forced_subs_only additionally to e.g. -slang en
if you are only interested in the forced subtitles.
For VobSub:
The idx file is now parsed for the "forced subs: ON/OFF" tag
and used according to its settings.
Key:
You can toggle the display of forced subtitles by pressing
"F" (upper case letter).
