Build 3.5.0.96 of xlsgen fixes the rendering of charts of type Area.

What is changed is how the bottom portion of the area surface gets rendered. Before this build, the plot area bottom would be the area bottom. Now this x axis (category axis) is the bottom, which means the area surface correctly crosses (if there is any negative data) or rests on the x axis instead of the bottom of the plot area.

This is mostly anecdotal change but it mimcs Excel.
