This makes me a little sad, but unfortunately, I see no reason why a TouchEvent
object can't be synthesized while specifying a cross origin view object. =(

I wonder why we even support that, since events can't be dispatched across
origin boundaries anyway.

Yeah I can't imagine a use case, but it would also be weird to add a special
case to the event creation system to disallow doing this.  The idea with event
creation is that script should be able to plumb whatever values it wants into
the events, even when the UA itself would never do that (eg. mouse events with
bogus/inconsistent co-ordinates).  So I think it's consistent with the larger
design there.
