  80 %  specified, the color value is changed for any neighbor pixel that does not
  81 %  match the bordercolor member of image.

  85 %  image defines how much tolerance is acceptable to consider two colors as
  86 %  the same.  For example, set fuzz to 10 and the color red at intensities of
  87 %  100 and 102 respectively are now interpreted as the same color for the
