     swfmovie->setbackground() sets the background color. Why is 
     there no rgba version? Think about it. (Actually, that's not such a dumb 
     question after all- you might want to let the HTML background show through.
     There's a way to do that, but it only works on IE4. Search the 
     http://www.macromedia.com/ site for
     details.)
