I think you're right.  GtkBuilder simply calls g_type_from_name to map a 
class name to a GType and then uses glib's built-in introspection 
mechanisms to construct the thing.  Implementing GtkBuildable is only 
necessary if you want to customize the construction, I think.

Are we missing something, muppet?
