I tought of a minimal way for now to get those things working in the
complete concept. Ommitting all the 10 bpc surfaces and also only
using 8 bit references is a quite a hacky approach. As I don't know of
any hw decoder that really does those things in 10 bits, I thought it
is enough to get the discussion started.

Presentation is a good aspect I did not have in mind.
