There were no more changes to the draft that affected what was in this
patch. However, from the muxer side, the last I checked there were still
players that bailed out on any unknown elements (e.g., chrome, when playing
back through media source extensions). And on the decoder, I've noticed an
issue when the matroska_track_video_color is not specified: the defaults
specified in the EbmlSyntax for this element were not propagated to the
nested struct. Let me address that one first.
