expose()

std::shared_ptr< Core::VKImage > MayaFlux::Yantra::VisionExtractor::expose	(	const std::shared_ptr< Core::VKImage > &	source,
		const Kinesis::Vision::VisionAnalysis &	analysis,
		float	target,
		uint32_t	source_w,
		uint32_t	source_h
	)

source scaled so its measured mean brightness reaches target.

Null without measure_appearance.
