| 31 | Each section below has two boxes, the top runs on the main thread, the bottom |
| 32 | on the compositor. The animations should be identical but start at different |
| 33 | times. |
| 34 | </p><p> |
| 35 | This test is successful if the each pair of boxes are mostly in sync (there |
| 36 | might be a small offset between them). |
