I have updated spu_RenderSubpictures and subpicture_region_t->pf_pre_render/pf_update_regions.

It now requires source format instead of scaling parameters.

Yes this creates a 'useless' picture copy per region, but it is
currently needed.

It is useless to wait for the first subtitle.

This properly creates the colorspace.

We still need the config options.

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.
