title: "weird" variable initialization
body: <p>What is meant by:</p>
  
  <pre><code>GLuint bindingPoint = 1, buffer, blockIndex;
  </code></pre>
  
  <p>I found this in one tutorial which I need, and I have never seen such a variable initialization before.</p>
  
  <p>Does this line mean</p>
  
  <pre><code>GLuint bindingPoint = 1;
  GLuint bindingPoint = buffer;
  GLuint bindingPoint = blockIndex;
  </code></pre>
  
  <p>?</p>
