100% isn't reliable. RequiresRzsize widgets have to be informed when their 
size change, so you have to give them a size that won't change on your 
behalf (I think EMs and EXs will be detected –i.e. when the user changes 
his browser font settings–, though probably not by each and every 
RequiresResize widget; better stick with pixels).
