        Have to mixin the SpriteSurface before deriving from

        implement some of those interface methods.

        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 explicitly 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.
