Thread-topic: Ooura FFT backend

Hi,

I noticed that the backends available today for Eigen are KISSFFT and FFTW3.. However, the Ooura FFT is around twice as fast as KISSFFT (at least acc. to http://www.fftw.org/speed/CoreDuo-3.0GHz-icc64/)
It seems that it only supports powerof2 sizes though, so is that why it hasn't been considered ?

Regards
/Robert
