     12 Each section below has two boxes, the top runs on the main thread, the bottom
     13 on the compositor.
     14 </p><p>
     15 This test checks that the compositor and main thread are performing identically
     16 given the same input parameters. This test is successful if each pairing of boxes
     17 are identical and all the boxes sync up and finish at the same time.
