I just want the histogram _data_. I'm not actually trying to create a
histogram graph itself. That is, I need an array of pixel count and
color code for each color in a GIF. The data will be used for other
purposes than building an actual graph of the color distribution.
JPGraph is designed to chart a distribution, once you have the data
for the chart. I need a way to get the raw data.
