title: What is the syntax for smoothing an embedded image with CSS?
body: <p>If I want to embed an image with smoothing I might do something like this:</p>
  
  <pre><code>package
  {
      public class EmbeddedImages
      {
          [Embed(source="/assets/image1.png", smoothing="true")]
          public static const Image1:Class;
      }
  }
  </code></pre>
  
  <p>However, if I have a bunch of buttons with different icons, I want to control which icon to display using CSS, like this:</p>
  
  <pre><code>@namespace s "library://ns.adobe.com/flex/spark";
  
  s|Button.image1
  {
      icon: Embed('/assets/image1.png');
  }
  </code></pre>
  
  <p>I want the icon to be smooth. So what is the syntax for adding smoothing when embedding with CSS?</p>
