title: Font size of title property of TitleWindow component in Flex
body: <p>How can I set font size of title property (header) in TitleWindow component? </p>
  
  <p>If I use fontSize property, it sets the font size for all components in TitleWindow, which is not what I want. I only want to set it for the title. </p>
  
  <p>I'm using <strong>Flex 3</strong></p>
  
  <p>Thank you</p>
