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.
