title: Space between handler and content in a SlidingDrawer
body: <p>When I try to use a SlidingDrawer in the horizontal orientation I get a space between the handler and the content. Any idea how I can get rid of it? In the vertical orientation I do not get a space.</p>
  
  <pre><code>&lt;SlidingDrawer
      android:id="@+id/module_trafic_map_drawer"
      android:layout_width="wrap_content"
      android:layout_height="match_parent"
      android:orientation="horizontal"
      android:topOffset="0dp"
      android:bottomOffset="0dp"
      android:handle="@+id/module_trafic_map_handle"
      android:content="@+id/module_trafic_map_content"&gt;
      &lt;ImageView
          android:id="@id/module_trafic_map_handle"
          android:layout_width="wrap_content"
          android:layout_height="match_parent" 
          android:src="@drawable/trafic_info_popup_right"
      /&gt;
      &lt;WebView
          android:id="@+id/module_trafic_map_content"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"            
      /&gt;
  &lt;/SlidingDrawer&gt;
