* UI Layout Callback: resizeTabLayout
*
* Requires Layout 1.3.0.rc29.15 or later

* This callback is used when a tab-panel is the container for a layout
* The tab-layout can be initialized either before or after the tabs are created
* Assign this callback to the tabs.show event:
* - if the layout HAS been fully initialized already, it will be resized
* - if the layout has NOT fully initialized, it will attempt to do so
* - if it cannot initialize, it will try again next time the tab is accessed
* - it also looks for ANY visible layout *inside* teh tab and resize/init it
*
* SAMPLE:
* $("#elem").tabs({ show: $.layout.callbacks.resizeTabLayout });
* $("body").layout({ center__onresize: $.layout.callbacks.resizeTabLayout });
