/* toolbar is a bit of a factory.  We will
represent this by making a virtual list called
tools.  Tools iterates through the children
of list.  It looks like list<Toolbar_Helpers::Tool*>
but inserts Toolbar::Element.  Elements
are a factory for spaces, widget, buttons, toggle
buttons and radio buttons.

The name "icon" in the gtk+ interface is very
misleading, it is really a button content
not a pixmap.  We will rename it to "content".

Confused?  Okay go read the interface.
