title: ploting filled polygons in python
body: <p>I have two matrices <code>Tri</code> and <code>V</code> for faces (Nx3) and vertices (Mx3) of polygons that I want to plot. Is there any matplotlib (or any alternative) way to do that? Something similar to Matlab command</p>
  
  <pre><code>patch('faces',Tri,'vertices',V,'facecolor', 
        'flat','edgecolor','none','facealpha',1)
  </code></pre>
