Who OK'd id? The ff_mdct_init change contains cosmetics and pointless code
duplication.
Also almost everyone uses a scale factor of 1, except vorbis, wouldn't
it possibly make more sense to instead add a ff_mdct_init_scaled with the
scale and leave the rest unchanged? I don't really know, just thinking.
I also wonder if it might be better if the calling code did the sqrt(),
for the current uses doing it in ff_mdct_init seems like it would only
add pointless complexity and possibly inaccuracies (or is e.g. sqrt(1.0) ==
1.0 always guaranteed by the C standard?).
