I fully intend to check out GtkPlaylist.  In the short term all
gst-player would need is a simple playlist widget. Longer term I'd like
to use that widget to:
- display audio cd tracks, including track names with freedb lookup
- display dvd chapter hierarchy

Bastien, do you think GtkPlaylist might go in this direction?

Another simpler solution might be to figure out how to embed
SDLVideoSink for the plebs who don't have Xv.

I'd like to give this a go, but would welcome any suggestions on how to
do it.

We need a png of the GStreamer slugs antialiased on a black background.

I intend to do an auto-hide, which is switchable with a gconf option.
