* Revision 1.23 2004/12/10 06:51:04 tobega Shamefully, I must now check in
* painfully broken code. Good news is that Layout is much nicer, and we also

* must be brought into line, but most needed is to fix Render. IMO Render
* should work with Boxes and Content. If Render goes for a node, that is wrong.
