ATM the yuv don't have any byte order annotations, and I simply left
them that way. So it is as clear/unclear as before.
IIRC someone mentioned that for the yuv fourccs there actually is some
standard about the exact ordering. Anyone has a good reference? We
could stick a link to it into a comment.
cheers,
Gerd
