How many do you need? How many byte-swapped variants of the other
formats do you need? You're scheme makes, like, 150 new formats right
away. How many are needed? I bet its something really small, like 3.
You're bits come out of the Bt848. Other hardware may not implement byte
swapping that way.

Sounds good. I'll add PIX_FMT_YYUV.
