title: CssResource defining only a Part of the Classes?
body: <p>I use GWT ClientBundle with CssResource.
  I have a css file test.css with the following classes:</p>
  
  <pre><code>.c1 {
  }
  
  .c2 {
  }
  </code></pre>
  
  <p>When I want to use classes from test.css I have to do the following in my application: </p>
  
  <pre><code>public interface Resources extends ClientBundle {
  
      @Source({Css.DEFAULT_CSS })
      Css css();
  }
  
  public interface Css extends CssResource {
  
      String DEFAULT_CSS = "buddyis/mobile/client/views/ItemView.css";
  
  
      String c1();
      String c2();
  }
  </code></pre>
  
  <p>The problem is that I have to define all the classes from test.css even if I don't use them. Is there a way that I have do define only the classes that I use?</p>
