title: How to change width of CubeGeometry with Three.js?
body: <p>I have a cube geometry and a mesh, and i don't know how to change the width (or height... i can change x, y and z though).
  Here's a snippet of what i have right now:</p>
  
  <pre><code>geometry = new THREE.CubeGeometry( 200, 200, 200 );
  material = new THREE.MeshBasicMaterial( { color: 0xff0000, wireframe: true } );
  mesh = new THREE.Mesh( geometry, material );
  // WebGL renderer here
  
  function render(){
      mesh.rotation.x += 0.01;
      mesh.rotation.y += 0.02;
      renderer.render( scene, camera );
  }
  
  function changeStuff(){
      mesh.geometry.width = 500; //Doesn't work.
      mesh.width = 500; // Doesn't work.
      geometry.width = 500; //Doesn't work.
      mesh.position.x = 500// Works!!
  
      render();
  }
  </code></pre>
  
  <p>Thanks!</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>Found a solution:</p>
  
  <pre><code>mesh.scale.x = 500;
  </code></pre>
