title: Change scale type to fitCenter for app style background image
body: <p>I am using a theme on my application so that when it start's up, the first thing a user sees is my background instead of an ugly black or white screen with an action bar on top. </p>
  
  <pre><code>&lt;style name="LoadingTheme" parent="android:Theme.Holo.Light.NoActionBar"&gt;
          &lt;item name="android:windowBackground"&gt;@drawable/loading_home&lt;/item&gt;
      &lt;/style&gt;
  </code></pre>
  
  <p>Simple enough. The problem is that, this screen transitions into my Splash page/Loading activity, which is displaying the same background image but with some scaling:</p>
  
  <pre><code> &lt;ImageView
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:scaleType="fitCenter"
          android:src="@drawable/loading_home"/&gt;
  </code></pre>
  
  <p>My issue is, that in my Splash page (the image view above), the background is displaying as I would like it, in that it does not look stretched (I believe due to fitCenter). However, in my application style, the background becomes stretched. Is there a way that I can apply scaleType to a background in a theme, or another method in which I can have control over the scaling of the background image in my application theme?</p>
