title: How to change the height of a TextField?
body: <p>If I create a <code>TextField</code> in ActionScript 3, I can change the width with a <code>TextFormat</code>, but how do I change the height?</p>
  
  <p>Example:</p>
  
  <pre><code>var label : TextField = new TextField();
  label.text = "Hello World!";
  label.background = true;
  label.backgroundColor = 0x800000;  // Red background to see TextField boundary
  label.autoSize = "center";
  
  var format : TextFormat = new TextFormat();
  format.leftMargin = 20;
  format.rightMargin = 20;
  
  label.setTextFormat( format );
  
  addChild( label );
  
  // Setting the height explicitly doesn't work
  label.height = label.width * 1.5;
  </code></pre>
