virtual std::optional< Rect >	GetSourceCoverage (const Matrix &effect_transform, const Rect &output_limit) const

virtual Matrix	GetLocalTransform (const Entity &entity) const
	Get the local transform of this filter input. This transform is relative to the `Entity` transform space. More...

virtual Matrix	GetTransform (const Entity &entity) const
	Get the transform of this `FilterInput`. This is equivalent to calling `entity.GetTransform() * GetLocalTransform()`. More...

virtual void	SetEffectTransform (const Matrix &matrix)
	Sets the effect transform of filter inputs. More...

virtual void	SetRenderingMode (Entity::RenderingMode rendering_mode)
	Turns on subpass mode for filter inputs. More...
