title: scaling without changing the position of THREE.Line
body: <p>I have line which is drawn between two vertices and using LineBasicMaterial. What I want to achieve is to increase the length of this line. I used </p>
  
  <pre><code>line.scale.z += 0.1;
  </code></pre>
  
  <p>on the object scaling it according to the direction in which it is drawn. This works but also messes up the position co-ordinates of the Line. So I had to update the position everytime with an offset on the scale change. Is there an easier way to increase the length? I'm a beginner in threejs, thanks for helping.</p>
