title: How do we translate a QML Rectangle on the Z axis, not just X and Y?
body: <p>Is it possible to translate a QML Rectangle on the Z axis similar to how we can do in HTML with CSS <code>transform:translateZ()</code> and <code>transform:translate3d()</code>?</p>
  
  <p>Applying <code>transform: Translate {x: 0; y: 0; z: 100}</code> on a Rectangle throws an error that the z property isn't defined.</p>
  
  <p>I am able to apply <code>transform: Rotation{}</code> to a Rectangle with a z-axis rotation and it looks 3D. I was hoping I could translate things in 3D as well.</p>
  
  <p>Is there a way to do it?</p>
  
  <p>EDIT: I tried setting a Matrix4x4 like this:</p>
  
  <pre><code>        transform: Matrix4x4 {
              matrix: Qt.matrix4x4(
                  1,0,0,0,
                  0,1,0,0,
                  0,0,1,10,
                  0,0,0,1
              )
          }
  </code></pre>
  
  <p>I set the number <code>10</code> where I believe the Z translation is, but the Rectangle just disappears instead of getting a little closer to the camera.</p>
