title: InvalidateSize without screen flash?
body: <p>Here's the scenario:  I wait for a creationComplete event to occur for an mx:Text object at which point I can access the setTextFormat method of its protected member textField.  (textField is not valid until creationComplete.)  At that point the text formatting done through textField.setTextFormat increases the height of the text.  But the mx:Text itself does not pick up this height change until I call invalidateSize.  However, in my case invalidateSize causes the entire text to be redrawn, causing it to flash on the screen.  However, if I just manually change the browser window size, the Text height change is made without the text flashing like that.  So how could I through a function call accomplish what is taking place when I manually change the browser window size.  (I just want mx:Text to pick up the height change accomplished through textfield.setTextFormat.)</p>
