| This test performs animations of the transform property on four boxes over 2 seconds. |
| Box 1 has all keyframes. Box 2 has a missing "from" keyframe. |
| Box 3 has a missing "to" keyframe. |
| Box 4 has both "from" and "to" keyframes missing, but other keyframes which |
| should trigger the generation of "from" and "to". Box 5 has no keyframes, and |
| should not animate. |
| The test takes 3 snapshots each and expects each result to be within a specified range. |
