No, I didn't think of that. I can revert it myself. But eventually it would be nice to have this
kind of code in cvs. Both AAC and AC3 use a KBD window. Maybe the code
should be in dsputil or belong to the mdct context? The same goes for sine MDCT windows, AAC,COOK,WMA
and I think IMC and ATRAC3 also uses the same type of sine windows.
