[Insight-developers] USE_FFTWF and USE_FFTWD and Exlicit Instantiation

[Kent Williams]

I discovered and corrected this error. Thanks for pointing it out! I 
didn't set the first element of the index for the output image region; I 
don't know why this didn't break tests before, other than the usual: 
happenstance in memory layout, dumb luck, etc.
