title: Set background color for Panorama Title
body: <p>I would like to set the background color of the title of a panorama.  I have done this by creating a DataTemplate and setting it to the TitleTemplate.  I then set the background color as such:</p>
  
  <pre><code>&lt;DataTemplate x:Key="PanoramaTitleTemplate"&gt;
      &lt;Grid Margin="0,50,0,0" Background="{StaticResource PhoneAccentBrush}"&gt;
          &lt;TextBlock Text="{Binding Content, RelativeSource={RelativeSource TemplatedParent}}" FontSize="133.333" /&gt;
      &lt;/Grid&gt;
  &lt;/DataTemplate&gt;
  </code></pre>
  
  <p>The problem is that on the last page of the panorama, the color doesn't fill the whole area.  It ends where the text ends.  I've tried setting the grid to a longer width, but not only does that still not fill the screen, it affects the title scrolling as well.</p>
