| we cannot specify non-IDL types as WeakComponentImplHelperN |
| template args, and furthermore, don't want to derive |
| ::canvas::CanvasCustomSpriteBase directly from |
| ::canvas::Sprite (because derivees of |
| ::canvas::CanvasCustomSpriteBase have to explicitely forward |
| the XInterface methods (e.g. via DECLARE_UNO3_AGG_DEFAULTS) |
| anyway). Basically, ::canvas::CanvasCustomSpriteBase should |
| remain a base class that provides implementation, not to |
| enforce any specific interface on its derivees. |
