Tests for using layoutAlign property rather than region, so design setting (headline or sidebar) has no effect. Remove for 2.0.
Basic layout. Tabindex="0" added to each pane to test for tab order matching source code order. Tab order should be: left, right, top, middle/main, bottom
Advanced layout. Tabindex="0" added to each pane to test for tab order matching source code order. Tab order should be: left, top, bottom, inner left, inner middle, inner right. This is not an ideal tab order. See below to use nested layout containers to achieve a tab order which matches presentation and source code order.
Advanced layout with nested containers. Tabindex="0" added to content panes to show tab order. Order should be: left, top, inner left, inner middle, inner right, bottom. This is the preferred tab order for this type of layout.
Goofy spiral layout. Match of source code order to tab order can not be achieved with this type of layout.
