// .NAME vtkImageFourierCenter - Shifts constant frequency to center for
// display.
// .SECTION Description
// Is used for dispaying images in frequency space. FFT converts spatial
// images into frequency space, but puts the zero frequency at the origin.
// This filter shifts the zero frequency to the center of the image.
// Input and output are assumed to be doubles.
