title: How to scale an entire scene in A-Frame?
body: <p>I have an A-Frame scene:</p>
  
  <pre><code> &lt;a-scene&gt;
        &lt;a-box position="-1 0.5 -3" rotation="0 45 0" color="#4CC3D9"&gt;&lt;/a-box&gt;
        &lt;a-sphere position="0 1.25 -5" radius="1.25" color="#EF2D5E"&gt;&lt;/a-sphere&gt;
        &lt;a-cylinder position="1 0.75 -3" radius="0.5" height="1.5" color="#FFC65D"&gt;&lt;/a-cylinder&gt;
        &lt;a-plane position="0 0 -4" rotation="-90 0 0" width="4" height="4" color="#7BC8A4"&gt;&lt;/a-plane&gt;
        &lt;a-sky color="#ECECEC"&gt;&lt;/a-sky&gt;
      &lt;/a-scene&gt;
  </code></pre>
  
  <p>How do I scale everything at once?</p>
