Detailed Description

Mixin Sprite.

Have to mixin the Sprite interface before deriving from canvas::CanvasCustomSpriteBase, as this template should already implement some of those interface methods.

The reason why this appears kinda convoluted is the fact that we cannot specify non-IDL types as WeakComponentImplHelper template args, and furthermore, don't want to derive canvas::CanvasCustomSpriteBase directly from canvas::Sprite (because derivees of canvas::CanvasCustomSpriteBase have to explicitly 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.
