title: Choose the Layer you want to draw to in PIL
body: <p>In PIL, can you choose the layer where you want to draw, so you don't draw every time ontop of everything?
  I am trying to draw an ellipse:</p>
  <pre><code>draw.ellipse(((0, 0), (200, 200)),fill=color)
  </code></pre>
  <p>which works just fine. But I want to draw another ellipse under the ellipse I just drew (drawing the next ellipse before the first ellipse isn't possible in my case). Can I set Layers or something, to draw an ellipse under another ellipse?</p>
