Unexpected rAF callback time value

Project Member Reported by aerotwist@chromium.org, Oct 4 2016

Issue description

http://jsbin.com/saqoxa/edit?js,console,output

I expected the window.performance.now() value inside the click handler to temporally precede the time value passed to the rAF callback, on the basis that the click handler should be scheduling the rAF callback for the next frame.

In Chrome on Mac (55.0.2880.0 canary), the rAF callback shows an earlier time than the click handler (see attached file).

In Firefox, Safari, and Edge the value in click precedes rAF's, so we seem to be the exception.

I think we decided that the fix here is to start giving rAF the glass time instead of vsync time.
