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