The GTK+ bug is still there, so we still need to hack glibmm for now,
but with that hack, I now have a working example:
http://cvs.gnome.org/viewcvs/gtkmm/examples/book/custom/custom_widget/

The secret (discovered on gtk-list gnome org) was that the style values
are only available when the widget has been realized. Luckily, that's
when we need them.
