Java3D's GraphicsContext3D object is creating that bitmap and our PNG is 
just saving it out.  The issue is that Java3D's not making a 
particularly sophisticated image.  It's mostly doing thresholding to the 
nearest object rather than nice smooth images.

Short of figuring out how to make Java3D make better images, we probably 
will need to make the images much larger (hence higher resolution), then 
scale them down nicely.  You can do this by hand by making the window 
MUCH MUCH bigger, say, 4 or 8 times bigger in each direction, and then 
taking the picture, saving it as a PNG, then scaling down in a picture 
editor.  You'll need to provide MASON with lot more memory. (like 
-Xmx400m or something).  I imagine we'd have to figure out how to do 
higher resolution images automatically.
