     BINARY ARITHMETIC OPERATIONS

     These routines use two images to produce a single output
     image.  They also may use a masking image to gate what is
     used from one of the input images.  The operations are
     arithmetic operations performed on a pixel by pixel basis
     from the two images.

     SHORT DESCRIPTION OF ROUTINES

     Addition -          Add two images pixel by pixel.

     Subtraction -       Compute the difference (subtract)
                         between two images pixel by pixel.

     Multiplication -    Multiply two images pixel by pixel.

     Division -          Divide two images pixel by pixel.

     Absolute Difference -
                         Compute the absolute difference between
                         two images pixel by pixel.

     Blend Images -      Blend two images using X*image1 + (1-
                         X)*image2, where X is the blend ratio.
