   Apache::lonprintout::page_size_state is an element that gives the 
   user the opportunity to further refine the page settings if they
   select a single-column page.
   
   page_size_state is always directly invoked in lonprintout.pm, so there
   is no tag interface. You actually pass parameters to the constructor.
