Log:
Rewrite i.fft, i.ifft
Output maps are FP
Don't use cell_misc/<map>/fft{real,imag} files, use the output maps
Don't rescale to powers of two (not needed with FFTW)
Use fft2() with FFTW-style interleaved array, not fft() with separate
real/imaginary arrays
Miscellaneous clean-up
backport this?
No specific ideas on this change, but if we're working towards a stable
settled down 6.x then I don't think the type of miscellaneous cleanups
that Glynn is doing in 7.x are candidates for backporting.
