You can now register a GWidget subclass with REGISTER_GWIDGET(class) and it will be available for factory construction through the new GWidgetClassRegistration interface. To obtain a GWidgetClassRegistration for a given class name, you call GWidgetClassRegistration::find(class_name). You can also iterate over all the registered classes using GWCR::for_each(callback). This will be very useful for implementing a proper GUI designer, and also in the future for things like script bindings. NOTE: All of the registrations are done in GWidget.cpp at the moment since I ran into trouble with the fricken linker pruning the global constructors this mechanism relies on. :^)
