Preliminary Fourier Transform Routines

[seanburke1979]

Hello everyone.
I have written some Fourier transform routines for (hopefully) inclusion in the MagickCore API. They rely on the FFTW library for the actual transform. The code is very fast, efficient, and *nearly* bug free! It supports all quantum depths, and hdri (if enabled) with the exception of Q32/HDRI (not sure why, still working on it).
I would like to get some testers together to review the code and the included documentation. If you have experience in IM development, please consider taking a few minutes to go over it.

(this link expires in one week. If some has a more permanent method of distribution, send me a message.)

Also, I am working on adding HDRI support to the IPL coder. I hope to have it up some time today.

We put your distribution in the contrib directory of the ImageMagick ftp sites. It takes 24 hours for the distribution to mirror world-wide.

After your get feedback from users and make any fixes and/or enhancements, let us know and we will look into integrating it into the ImageMagick trunk.

Great!
