        Have to mixin the Sprite interface before deriving from
        ::canvas::CanvasCustomSpriteBase, as this template should
        already 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::CanvasCustomSpriteBase directly from
        ::canvas::Sprite (because derivees of
        ::canvas::CanvasCustomSpriteBase 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.
