[Bug 20713] Consider defining window.event and Event.srcElement

https://www.w3.org/Bugs/Public/show_bug.cgi?id=20713

--- Comment #16 from Philip Jägenstedt <philipj@opera.com> ---
Some things from the Blink bug:
https://code.google.com/p/chromium/issues/detail?id=223749

First, the use counter is over 3%:

That cannot be an accurate estimate of the risk of removing window.event in
Blink, so we need better data. Is the only case worth measuring when
window.event is non-undefined while accessed from a non-inline event listener,
like in this following?

x.addEventListener('click', function() {
  if (event.type == 'foo')
    bar();
});

Also, I learned that there's a difference between SVG and HTML:
https://code.google.com/p/chromium/issues/detail?id=223749#c10

Of the three end states mentioned there, does any seem more worth aiming for,
or are there other, better, end states?
