KNOWN BUGS

1. There's a serious bug in picking of ValueGrid2DPortrayal3Ds, as is
   noted in the tutorials.  Sun claims that this is an expected misfeature
   of the spec; it'll likely force us to move to triangles rather than
   quads.

2. We need better HTML text for some demos.

3. To get the 3D code in-line with the 2D code, the following field
   portrayals would have to be implemented (and haven't yet):

	ObjectGridPortrayal3D
	ValueGridPortrayal3D
	NetworkPortrayal3D

4. Our handling of inspection of arrays, maps, lists, etc., is still flakey.

5. If you close the window of a 3D display, the system pauses.  This is due
   to certain dorky misfeatures of Java3D.  We can get around it in theory
   but aren't sure how much work we'd want to put into that.

6. If you close the window of a 3D display on MacOS X, then open it again,
   the display doesn't come back.  This is a bug in Apple's code, and we'll
   let them know.

7. Java3D textures are awful looking.  Oh well!

8. MacOS X 1.4.x draws many objects (circles, rects) one pixel taller and
   wider than they're supposed to be.

9. We've not updated the diagrams to reflect the new MASON class names.
