This fixes bugs when loading non-VLC generated XSPF playlists.

First, set a text drop shadow because we can, and it is nice for readability.
Then, correct behaviour for border color: minimum size to 1.0, where current code max it to 1.0, and comment the contrary.

so we can install VLC in non-ANSI-named directories

(As pointed by Remi)

Note, this doesn't work with just exec() for some obscure reason.

It has a bad side effect when using software rescaling: the subtitles are
rendered using the video original size instead of the display one (like with
overlay). I will fix that latter.

(The PTS delay thing should be dynamically automatically computed -
 for every access - however, IMHO)

This is the issue exploited by the anime groups.
We now skip anything in { }
Note that ass/ssa cannot have a valid string with text { text } text.

So that the dialog won't pop up again.

I've had it with this module. There is no support, let alone development, from the matroska folks anymore. I prefer to use ffmpeg which seems to be at least less crash prone and having more of a future. I'm not sure which features we are loosing due to this atm. Likely some meta info, probably ordered chapters and definetly the DVD menu capabilities.

I removed:
 i_x/i_y: redondant with region i_x/i_y. Now a subpicture always represent the
 whole video.
 i_flags: unused anywhere in the core.

 I may have broken a few video filters (osdmenu mainly). I will fix it if you
report the problem and the way to reproduce it.

Fix unitialized pointer usages (possibly exploitable).

There is no functional changes.
