So here is my second work in progress patch set. These are the functions from the second half of my previous.
With Ronald's rounding contribution I am much closer to finishing. As I mentioned on IRC I think the speed of decoding an MPEG2 HD sample has increased from 215 to 235 fps. I still have a small optimisation to make and I need to use the correct coefficients. This will require a large change to the macros. I am sending this so that people can nitpick my changes.
