* Introduce a Directionality inherited widget which sets the ambient LTR vs RTL mode (defaulting to null, which means you cannot use directionality-influenced values). * Make it possible to configure Padding (including Container.padding and Container.margin) using a directionality-agnostic EdgeInsets variant. * Provide textDirection and verticalDirection controls on Row and Column to make them RTL-aware. * Introduce a variant of FractionalOffset based on the EdgeInsets variant. Not yet actually used. * Fix all the tests that depended on Row defaulting to LTR.
