title: editText lineSpacingExtra issue
body: <p>I have an editText with layout:</p>
  
  <pre><code>&lt;EditText
          android:id="@+id/edittext"
          android:layout_height="wrap_content"
          android:layout_width="fill_parent"
          android:text="test"
          android:layout_margin="5dp"
          android:gravity="left|center_vertical"
          android:lineSpacingExtra="10dp"
          android:lineSpacingMultiplier="1"
          /&gt;
  </code></pre>
  
  <p>but the text is not centered vertically because of <code>lineSpacingExtra</code>. Here is how it looks:</p>
