-- <description>
-- This package implements a general button widget. This button can be
-- clicked on by the user to start any action. This button does not have
-- multiple states, it can just be temporarily pressed while the mouse is on
-- it, but does not keep its pressed state.
--
-- The gtk+ sources provide the following drawing that explains the role of
-- the various spacings that can be set for a button:
