    Pass Criteria
  
  
The test shows four smiley images: the leftmost one is the reference,
      and the three on the right are the three sub-tests.  The test is passed
      if the following conditions are met:
      
        - The image in the first sub-test is shown within the blue rectangle,
        its aspect ratio preserved and with white bars between the blue rectangle
        and the left and right edges of the image.
- The image in the second sub-test is shown within the blue rectangle,
        its aspect ratio preserved and with white bars between the blue rectangle
        and the top and bottom edges of the image.
- The image in the third sub-test is shown stretched, having the same
        size as the blue rectangle shown on the left of the test slide underneath
        the text "Viewport 2".
