     TRANSFORMS

     These routines are used to go to and from the Fourier Domain
     and perform operations in the Fourier Domain.

     SHORT DESCRIPTION OF ROUTINES

     2D FFT -            Compute the two-dimensional
                         Forward/Inverse Fast Fourier Transform
                         (FFT).

     2D Hadamard -       Compute the two-dimensional
                         Forward/Inverse Fast Hadamard Transform
                         (FHT).

     2D Mag, Power, Phase-
                         Compute 2D magnitude, power, or phase
                         spectrum information. (formerly vspec-
