Can we use use new-style header here?

That's weird. I'm pretty sure I copy pasted the new chromium copy right here.
But I guess I lost that part of the change. I'll fix it.

Done.

WebScopedCoalescedInputEvent or ScopedWebCoalescedInputEvent maybe? :)

[Navid Zolghadr, 2016/12/16 15:38:09]

Sure. How about ScopedWebInputEvent? Do you like that also to be
WebScopedInputEvent?

[Navid Zolghadr, 2016/12/22 20:50:33]

I changed them all to start with Web
