/** 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 WeakComponentImplHelperN
|
|
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.
