I've used FFTW from within IDL (using a DLM) in the past and it was a lot
faster than the IDL FFT routine. I used a DLM wrapper set up by our old
friend, S.V.H. Haugan. However, my current installation does not work since
I have not updated it for IDL6.0. I'll see if I can get it working, and I'll
report back on my findings.
