title: WrapPanel doesn't wrap in WPF ListView
body: <p>I am using a ListView with an ItemTemplate like this:</p>
  
  <pre><code>&lt;Window.Resources&gt;
      &lt;DataTemplate x:Key="ItemTemplate"&gt;
          &lt;WrapPanel Orientation="Horizontal"&gt;
              &lt;Image Width="50" Height="50" Stretch="Fill" Source="{Binding Cover}"/&gt;
              &lt;Label Content="{Binding Title}" /&gt;
          &lt;/WrapPanel&gt;
      &lt;/DataTemplate&gt;
  &lt;/Window.Resources&gt;
  </code></pre>
  
  <p>But the Covers do not fill the screen like windows explorer windows.</p>
  
  <p>How do I do this? They just get stacked vertically in my version.</p>
