/**
* \class ScalarToRGBPixelFunctor
* \brief A Function object which maps a scalar value into an RGB pixel value.
*
* This class is useful for visualizing labeled images which cannot be mapped
* succefully into grayscale images. Images of unsigned long integers, for
* example, may have too many graylevels to visualize effectively.
*
* The hashing scheme used is designed to spread close scalar values of very
* different colors by using the least significant bits (fastest changing) of
* the scalar type to determine the color. Because labeled images may
* typically use sequential values, it is desirable that those values result
* in easily discernable colors.
