title: Usefull way of reverting Homogeneous coordinates back to 2d?
body: <p>Is there some numpy sugar for reverting Homogeneous coordinates back to 2d coordinates. </p>
  
  <p>So this:</p>
  
  <pre><code>[[4,8,2],
  6,3,2]]
  </code></pre>
  
  <p>becomes this:</p>
  
  <pre><code>[[2,4],
  [3,1.5]]
  </code></pre>
