that results in the calculator widget taking up all available space the
and hbox11 being too short/small.  If I use FALSE, FALSE there is no
need to use an alignment.  I want the hbox11 buttons to grow, but not
too much.  I also want the calculator buttons to be a good middle of the
road size.  and I want no space between.

- I want *all* the excess space consumed.
- I want some of the space to be used by the calculator, and
- I want some space to be consumed by the buttons in hbox11.

currently:
- If I set expand on *any* widgets to FALSE, they end up too small.
- If I set expand on *all* widgets to TRUE, some widgets take up more
  space than I want them to.
- If I try to use a GtkAlignment object to control the growth of the
  widgets that are getting too big, I create *excess* space that is not
  consumed by uncontrolled widgets.
