How is this different from saying we should have gtk_entry_draw(),
gtk_button_draw(), etc. instead of gtk_widget_draw()?

The point of inheritance is that an object is_a GTypeInstance, so you
can call GTypeInstance methods on it. Type checks are supposed to
catch type errors, passing an instance there is not a type error.
