nit: MoveTo() might be a better name for this method

If you add this method to RenderWidgetHostView, you'll need to add
implementations for all subclasses, not just the Linux one.

Yes, you are right.

So once this solution is Ok only in Linux, I'll start implement Mac.

But, as I used to say, I don't have any Windows dev env.
So I might ask somebody to implement Win.
