GainMap is where the HDR gain-map data will be stored. It is going to be serialized to GPU process through ShareableGainMap. The members of GainMap are: a CVPixelBuffer for the gain-map image, image-metadata and colorspace. ShareableGainMap will be responsible for generating the HDR image from the base image and the gain-map.
