Ogg Vorbis decoder for SoundDecoder directly adapted from SDL_sound's code. Thanks to Johnson Lin for providing this! Instead of trying to backport my Tremor decoder which originated from the SDL_sound Vorbis decoder, I told Johnson it would be better to just start at the source and avoid all the original gotchas I hit in the subtle differences between Tremor and Vorbis. Since this derives directly from Ryan Gordon's SDL_sound implementation, I am putting this under the LGPL subdirectory. Johnson Lin < arch . jslin - at - gmail . com >
