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