It depends on how JACOsub uses the palettes afterwards.

Just here: transition and compatibility: converting the existing decoders to
this new API would take time, even if it makes them simpler in the end. In
the meantime, they will still fill the rect->ass field even if we consider
it deprecated. So we can use it.

That is similar to interleaving samples until mplayer can handle planar
formats: we want to get rid of it, but we do not want to break things during
the transition.
