Hi all,

New release: this time it actually works ;-)

... plus the final matrix transpose which they forgot :-)

I'll be on holiday for a week; I figured I'd send this off since it is
in a working state ;-) Diff should apply to both 0.2.82 and 0.2.83.

Have fun!

Michel

PS this is not Paul's IDCT, which I plan on integrating later on and
compare performance and accuracy against Motorola's.
