title: Why is Face detection only working with CGImagePropertyOrientation.right?
body: <p>I've created the Xcode project available on the link below in order to explore the new Vision Framework released by Apple with Xcode9. It is based of adjustments made on codes I've found both on GitHub and Youtube, but I can't understand why the CGImagePropertyOrientation.right on the orientation parameter on the VNImageRequestHandler. Can someone shed a light on this?</p>
