  53
  54         Have to mixin the Sprite interface before deriving from
  55         ::canvas::CanvasCustomSpriteBase, as this template should
  56         already implement some of those interface methods.
  57
  58         The reason why this appears kinda convoluted is the fact that
  59         we cannot specify non-IDL types as WeakComponentImplHelperN
  60         template args, and furthermore, don't want to derive
  61         ::canvas::CanvasCustomSpriteBase directly from
  62         ::canvas::Sprite (because derivees of
  63         ::canvas::CanvasCustomSpriteBase have to explicitly forward
  64         the XInterface methods (e.g. via DECLARE_UNO3_AGG_DEFAULTS)
  65         anyway). Basically, ::canvas::CanvasCustomSpriteBase should
  66         remain a base class that provides implementation, not to
  67         enforce any specific interface on its derivees.
