Just to point out an issue, if the image comes out grainy, it's likely 
the display depth is set at 16 bit instead of 32 bit, kick up squeaks 
display depth and this won't happen.  I ran into the same issue when 
using PieChart's and PlotMorph's.  Look in the world menu under 
appearance/display depth.
