Comment (by heleppkes):
Just to get some clarity..
You quoted a matrix you used for qaac, and you said this matrix gives you
a good result, right?
This quoted matrix has two negative operations for Lt, and two positive
operations for Rt, just like the swresample code (BEFORE the patch!).
If anything, the coefficients may be slightly wrong, but the +/- are in
the proper places from what I can tell.
