[requestAnimationFrame] Test Suite

Karen has submitted the requestAnimationFrame test suite to the submission folder. Please take a moment to review the test suite and provide feedback. The tests are here: http://w3c-test.org/webperf/tests/submission/Microsoft/requestAnimationFrame/test_paint.htm.

The test suite is testing the unprefixed API. If you want to test your prefixed implementation, update the following variables in the paintnotificationharness.js file:

var reqAnimAPI = window.requestAnimationFrame;
var cancelAnimAPI = window.cancelRequestAnimationFrame;

We have verified that IE10 and Chrome pass the test suite. Boris, can you check Firefox?

Thanks,
Jatinder
