title: How to set the application icon for a libGDX desktop application?
body: <p>I am trying to setup an application icon from the -desktop specific class with:</p>
  
  <pre><code>package org.osgameseed.games.animalflip;
  
  import com.badlogic.gdx.Files;
  import com.badlogic.gdx.backends.lwjgl.LwjglApplication;
  import com.badlogic.gdx.backends.lwjgl.LwjglApplicationConfiguration;
  
  public class Main {
      public static void main(String[] args) {
          LwjglApplicationConfiguration cfg = new LwjglApplicationConfiguration();
          cfg.title = "AnimalFlip";
          cfg.useGL20 = false;
          cfg.width = 800;
          cfg.height = 600;
          cfg.addIcon("data/ic_launcher.png", Files.FileType.Internal);
  
          new LwjglApplication(new AnimalFlipGame(), cfg);
      }
  }
  </code></pre>
  
  <p>The icon is not set (at least on Linux), any idea on how to set it ?</p>
