[MPlayer-dev-eng] [PATCH] Remove font attributes from subtitles

[Robert Ramiega]

  Hi!
Sometimes subtitles files (i've seen this in mdvd and mpl2 only) contain
information on attributes of the following subtitle (like italics or color).
As of now mplayer just displays this information as part of subtitle. So far
i couldn't make head or tails out of subtitle rendering in mplayer so i made
small patch that removes this extranous information. 
 If someone would be so nice and get me started on subtitle rendering i'm
willing to try to make mplayer actually recognize and use this attributes.

Here is sample subtitle:

[01][19]{C:$aaccff}Battlestar Galactica [1x02]
Water|/{C:$aaccff}http://napisy.gwrota.com
[15][35]{C:$aaccff}/Poprzednio w Battlestar Galactica...
[40][70]{C:$aaccff}CYLONI ZOSTALI STWORZENI|{C:$aaccff}PRZEZ CZLOWIEKA.
[76][106]{C:$aaccff}ZBUNTOWALI SIE.
[112][137]{C:$aaccff}EWOLUOWALI.
[147][167]{C:$aaccff}WYGLADAJA
[171][184]{C:$aaccff}I CZUJA
[185][200]{C:$aaccff}JAK LUDZIE.
