gtkrc , pixmap engine, and button widgets

["Boncek, John" <jboncek Hunter COM>]

We are using gtkrc with the pixmap engine to have a brushed-aluminum look
on button widgets.  It looks great, but it also disables the default
behavior in which the button appears to press inward when clicked on.  Is
there a way to achieve this with the pixmap engine?  For instance, is
there a way to associate different pixmaps with the button based on the
button's state (active vs. normal state)?  I've done quite a bit of
Googling and searching of this list to no avail.
