  52
  53         Have to mixin the Sprite interface before deriving from
  54         ::canvas::CanvasCustomSpriteBase, as this template should
  55         already implement some of those interface methods.
  56
  57         The reason why this appears kinda convoluted is the fact that
  58         we cannot specify non-IDL types as WeakComponentImplHelper
  59         template args, and furthermore, don't want to derive
  60         ::canvas::CanvasCustomSpriteBase directly from
  61         ::canvas::Sprite (because derivees of
  62         ::canvas::CanvasCustomSpriteBase have to explicitly forward
  63         the XInterface methods (e.g. via DECLARE_UNO3_AGG_DEFAULTS)
  64         anyway). Basically, ::canvas::CanvasCustomSpriteBase should
  65         remain a base class that provides implementation, not to
  66         enforce any specific interface on its derivees.
