+
+        The reason why this appears kinda convoluted is the fact that
+        we cannot specify non-IDL types as WeakComponentImplHelperN
+        template args, and furthermore, don't want to derive
+        ::canvas::SpriteCanvasBase directly from
+        ::canvas::SpriteSurface (because derivees of
+        ::canvas::SpriteCanvasBase have to explicitely forward the
+        XInterface methods (e.g. via DECLARE_UNO3_AGG_DEFAULTS)
+        anyway). Basically, ::canvas::CanvasCustomSpriteBase should
+        remain a base class that provides implementation, not to
+        enforce any specific interface on its derivees.
