As far as I know, there's nothing at all controversial about the libgsf
style of macro that defines the entire get_type() function. That is,
everybody who has commented on it thinks it's a good idea. Still haven't
heard from Tim.

The BONOBO_BOILERPLATE style with the prototypes for class_init and init
and the class_init trampoline to set the parent type, I think *is*
to comprehensive. Plus, it doesn't do interfaces.

But I like the libgsf style a lot.
