title: EditText Drawable Tint not possible?
body: <p>I use tint for icons for whole my app. </p>
  
  <p>Example in my <code>ImageView</code>:</p>
  
  <pre><code>&lt;ImageView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_gravity="center_vertical"
      android:src="@drawable/ic_account_circle"
      android:tint="@color/red_color"/&gt;
  </code></pre>
  
  <p>I also use some of the icons in <code>EditText</code> as its drawable:</p>
  
  <pre><code>&lt;EditText
      android:id="@+id/passwordInput"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:drawableLeft="@drawable/ic_lock"
      android:drawablePadding="@dimen/medium_margin_padding"
      android:hint="@string/password_text"
      android:inputType="textPassword" /&gt;
  </code></pre>
  
  <p>However, I can't find any code that can be used to tint the drawable in <code>EditText</code>. Is it not possible to tint the drawable?</p>
  
  <p><strong>Note:</strong></p>
  
  <p>I use appcompat and design support library, but still can't find any code.</p>
