This doesn't seem to do anything in this patch? Please remove and use in the
next patch?

I was going to wait until the connector patch to actually dispatch this event
(from GuestViewBase::SetSize()), but I will temporarily dispatch it from the
current sizing locations in GuestViewBase for now so that this constant gets
used and also so there is actually a path to the onResize code in guest_view.js.
