We've had the H.264 Frame Packing SEI for ages now; as far as I can
tell, no real people actually care enough to want it...

I assume these Matroska tags allow us to e.g. have a 1920*2160 image,
the top half of which is one view and the bottom half of which is
another view?  Because that's the sensible way to do it.
