title: UIImagePickerController's cameraOverlayView is offset after taking photo
body: <p>When you implement a <code>cameraOverlayView</code> for a <code>UIImagePickerController</code>, this view appears while you're taking the photo and after the photo has been taken, providing you with an opportunity to cancel or retake the photo. The problem I'm seeing is if your <code>cameraOverlayView</code> is on top of the photo preview area, when you take the photo and it shows you the preview, the photo you took doesn't align with the <code>cameraOverlayView</code> anymore. The entire photo preview pane has been moved down ~50 points while the <code>cameraOverlayView</code> has stayed in place. This is a problem when you need the photo to be aligned perfectly with the view.</p>
  
  <p>How can this be adjusted so the two are perfectly aligned - while taking the photo and after it has been taken?</p>
  
  <p>Notice how the whole preview area is pushed down after taking the photo.</p>
