wxBorderSizer
This sizer provides an empty buffer on one or more sides of it's
contents. It can only hold a single widget, but that can be a
sizer containing other items if you wish.
The sizer is constructed with a parameter specifying which sides
should have the border. You can use a logical OR of the following
values to specify the sides:
wxNORTH -- the top side
wxSOUTH -- the bottom side
wxEAST -- the right side
wxWEST -- the left side
wxALL -- all sides
The width in pixels of the border is specified when the child
widget is Added to the sizer.

# TODO... Make an abstract class wxBorder whose decendants can be added to
# a wxBorderSizer to provide drawing for the buffer area. Ideas are
# to provide a color border, beveled borders, rounded borders, etc.
