Fast Fourier Transform.
vtkImageFFT implements a fast Fourier transform. The input can have real or complex data in any components and data types, but the output is always complex doubles with real values in component0, and imaginary values in component1. The filter is fastest for images that have power of two sizes. The filter uses a butterfly fitlers for each prime factor of the dimension. This makes images with prime number dimensions (i.e. 17x17) much slower to compute. Multi dimensional (i.e volumes) FFT's are decomposed so that each axis executes in series.

Used internally for streaming and threads. Splits output update extent into num pieces. This method needs to be called num times. Results must not overlap for consistent starting extent. Subclass can override this method. This method returns the number of pieces resulting from a successful split. This can be from 1 to "total". If 1 is returned, the extent cannot be split.
