Please also note that, though I would like to investigate any problem
with this, I doubt that it's a good idea to implement a GTK+ theme
engine with gtkmm. Theme engines need to be very fast very often.

Usually, when someone says that GNOME is slow, they are using some
strange theme engine.

A few extra function calls don't make any difference in an application
that spends most of it's time waiting for the user, but you might notice
it in a theme engine. However, I haven't tried it, and guessing is no
way to do optimisation.
