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