title: How to position radial gradient background
body: <p>How can I position a radial gradient shape as background in a LinearLayout ? Here is what I presently have :</p>
  
  <p>The shape :</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;shape xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;gradient
          android:endColor="#e6e6e6"
          android:gradientRadius="800"
          android:startColor="#fafaf9"
          android:type="radial"/&gt;
  &lt;/shape&gt;
  </code></pre>
  
  <p>The LinearLayout :</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout 
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:orientation="vertical" 
      android:layout_width="fill_parent"
      android:layout_height="fill_parent" 
      android:background="@drawable/accueil_bg_gradient"&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>I just want to have my gradient starting from the left upper corner of the screen, and ending at the right lower corner.</p>
  
  <p>Thanks a lot !</p>
