CGImageCreatePixelBufferAttributesForHDRTarget() is to get the attributes of the
target CVPixelBuffer. The target pixel format is set explicitly to 'RGhA'.
Instead of calling VTCreateCGImageFromCVPixelBuffer(),
CVPixelBufferGetIOSurface()
and CGImageCreateFromIOSurface() are used to get a CGImage from the target
CVPixelBuffer.
