5"""Impact HTML5 Gaming benchmark.

7Tests 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
9browser spent rendering frames (formula is 1000000/(sqrt(totalTime) + lagTime *
100.1)). The benchmark automatically runs at a reasonable screen size. Final
11score is a indicator for the browser's ability to smoothly run HTML5 games."""
