/**

  This is a custom version by Mike Challis
  http://www.carmosaic.com/weather/scripts.php
  Modified to resize a WDL swf http://www.carmosaic.com/weather/live.php
  modified to rezize wdl based on width of "flashcontent" div rather than screen width
  This version is customm tailored for the Weather Display/PHP/AJAX Website Template set wdl page or mml page
  this allows function settings to pad the bottom of the page and make room for any content below the swf
  this assumes that the swf 'flashcontent' div is inside a 'main-copy' div that is inside a 'page' div
  as standard for the Weather Display/PHP/AJAX Website Template set wdl page or mml page
  or it will not work!
