If we make nsIEditor a builtin class, that means that its instance can be only TextEditor or HTMLEditor. Then, users of nsIEditor can use concrete classes such as EditorBase, TextEditor or HTMLEditor instead. Then, the users can reduce unnecessary QI and a lot of virtual calls if we'll create non-virtual methods. So, let's make editor related interfaces builtin classes.
