I wrote that I thought there was a bug with alignment in vboxes.  The problem
was that the following code fragment didn't seem to work right:

	layout.hbox(layout.vglue(5 * 70),
                    layout.vbox(layout.vglue(),
                                new Circle(100, kit.foreground(), 
                                           new Brush(1.0)),
                                layout.vglue()));

After tracing through various execution paths and staring at the code for
a few more hours, I saw that if the alignment of the first vglue object
was set to 1.0, then things would work.  E.g., the following code "solves"
the problem outlined in my previous message:

	layout.hbox(layout.vglue(5 * 70, fil, 0, 1.0),
                    layout.vbox(layout.vglue(),
                                new Circle(100, kit.foreground(), 
                                           new Brush(1.0)),
                                layout.vglue()));

Is my fix just a bug workaround, or is this really what you have to do to make
it work?  If the latter is true, I'm confused.
