I did not follow this discussion but if this is about muxing bitmaps as
subtitles then I don't understand why vobsub or any other future
filter/renderer doing the painting needed to know about the storage format
of the pictures. Multiplex every kind of subpictures like idx/sub or bmps as
png and the demuxer will output it as an uncompressed subtitle image towards
the renderer.
