Support for graphic subtitle formats in cutscenes

Well, because of the beginning discussion in the Forums: [https://www.hard-light.net/forums/index.php?topic=94802.msg186906](url) and the up- and downsides of SRT files, i create this issue here, because i made my reasons why SRT is not a desireable format for me right now.

So i simply want to see support for subtitles that are based on a graphical layer, as far as i know SUB/IDX (also used on DVDs back then) and PGS (also used on BluRays today) are the most common ones these days. Even they are hard to create, because they are graphic files, they surely would make downloads much smaller without to download whole language specific cutscenes (and yes, i see the downsides of this as well). And you will not have any limitations in the creation of a subtitle, because it is a layer above the video track you can design like you want.

Because i am maybe the only one who would ever use this feature i actually do not see that this will be implemented (which i also can understand ^^). But i wanted to bring it up at least (once again after a discussion in an older topic as well)
