When decompressing an image that was compressed using chrominance
subsampling, use the fastest chrominance upsampling algorithm available in
the underlying codec. The default is to use smooth upsampling, which
creates a smooth transition between neighboring chrominance components in
order to reduce upsampling artifacts in the decompressed image.
