57 
58     	Have to mixin the Sprite interface before deriving from
59     	::canvas::CanvasCustomSpriteBase, as this template should
60     	already implement some of those interface methods.
61 
62         The reason why this appears kinda convoluted is the fact that
63         we cannot specify non-IDL types as WeakComponentImplHelperN
64         template args, and furthermore, don't want to derive
65         ::canvas::CanvasCustomSpriteBase directly from
66         ::canvas::Sprite (because derivees of
67         ::canvas::CanvasCustomSpriteBase have to explicitly forward
68         the XInterface methods (e.g. via DECLARE_UNO3_AGG_DEFAULTS)
69         anyway). Basically, ::canvas::CanvasCustomSpriteBase should
70         remain a base class that provides implementation, not to
71         enforce any specific interface on its derivees.
