-- /* Size Groups
--  *
--  * GtkSizeGroup provides a mechanism for grouping a number of
--  * widgets together so they all request the same amount of space.
--  * This is typically useful when you want a column of widgets to 
--  * have the same size, but you can't use a GtkTable widget.
--  * 
--  * Note that size groups only affect the amount of space requested,
--  * not the size that the widgets finally receive. If you want the
--  * widgets in a GtkSizeGroup to actually be the same size, you need
--  * to pack them in such a way that they get the size they request
--  * and not more. For example, if you are packing your widgets
--  * into a table, you would not include the GTK_FILL flag.
