/*
* This plug-in for The Gimp uses the algorithm described below to map
* a source image to a destination image. Two grayscale images X and Y
* are used to describe the mapping.
*
* For each position in the destination image, get the luminosity of the
* pixels at the same position in the X and Y images. Interpret this pair
* of values as a coordinate pair. Copy the pixel at these coordinates in
* the source image to the destination image.
*
* The latest version and some examples can be found at
* http://www.best.com/~schubart/cm/
*
* This is my first plug-in for The Gimp. You are very welcome to send
* me any comments you have.
