##
# Equalize the image histogram.  This function applies a non-linear
# mapping to the input image, in order to create a uniform
# distribution of grayscale values in the output image.
#
# @param image The image to equalize.
# @param mask An optional mask.  If given, only the pixels selected by
#     the mask are included in the analysis.
# @return An image.
