In general, it'd be useful also for ID3 tags, which can contain album covers.
See the GST_TAG_IMAGE comment, also.

In this case:
1) several movies contain a single-image stream and a real video stream. We
want to distinguish between those. The image is probably a cover or screenshot,
whereas the movie is to be played. Those are not to be confused, and we should
not allow the user to "switch". So at a playbin level, they need to be handled
differently.
2) the easiest way to do that is by doing them differently at the demuxer
level, and in this case, I figured that doing so as a tag would be a good idea,
since it basically is stream metadata.
3) this does not keep the xv resource busy while we "play" the extra stream.
Also, it does not have any pipeline overhead for display, you merely use a
GdkPixbuf.
4) 0.8 has a very poor "keep display on eos" concept and no "display on
startup". So the user experience as a GdkPixbuf will actually be better.
