The test appears to make progress, but then after a few seconds gets stuck and no progress can be observed for minutes. When you close the window, the main tab with RoboHornet in it spontaneously refreshes, saying "A problem with this page caused Internet Explorer to close and reopen the tab."
Running the test in standalone reports that it completes successfully in 2 ms.
No script errors are observed.
in IE 10 it takes a loong time to complete. Maybe gets slower as it goes? Seems to do a lot of repeated line draws, then clears, then line draws over and over for a really long time. It reports 3752.63ms but it took what seems like 5 minutes to complete.
Rewrite the canvasdrawline benchmark to draw many very short paths in…
…stead of one very long one, and also reduce the size of the test. This allows it to complete in Safari, IE, and Firefox on the golden master machine, and fixes #39, fixes #40, and fixes #41.
