I had to add back document.createText() since new Text() does not work in the new world yet. LayoutRoot is a new Dart-exposed class which holds the Frame and all associated machinery, sufficient to trigger a restyle and layout of the subtree. This is all kinda hacky and I'm sure likely to cause many crashes if folks call random methods on these disconnected trees. But this makes it at least possible to paint text for now and we can improve this in the coming days. This really should have Adam's review. It's hugely hacky but I'd like to negotiate out with him the timeline on which we should fix some of these hacks.
