   7 Tests one very specific use case: smooth running games rendered with the
   8 <canvas> element. The score for the HTML5-Benchmark takes the total time the
   9 browser spent rendering frames (formula is 1000000/(sqrt(totalTime) + lagTime *
  10 0.1)). The benchmark automatically runs at a reasonable screen size. Final
  11 score is a indicator for the browser's ability to smoothly run HTML5 games."""
