The BoxSizer simply lays out its items in either a horizontal row, or
a vertical stack.  This is the sizer's primary dimension.  Items can
be added such that they get only their minimal size needed, or a
proportion of the available free space.  In addition, items can expand
to fill all available space in the alternate dimension.
