This patch does a number of things, unfortunately all at once: * Hoists a large subset of the layout wrapper functionality into the style system. * Merges TElementAttributes into the newly-created TElement. * Reorganizes LayoutData by style vs layout, and removes LayoutDataShared. * Simplifies the API for borrowing style/layout data. There's still more to do to make the style system usable standalone, but this is a good start.
