title: SCNText with background view having color and corner radius
body: <p>I have a requirement to add some text (for example, count) to the scene kit. The text has some background color and that background must be in circular shape as shown below:</p>
  
  <p><a href="https://i.stack.imgur.com/t47bn.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/t47bn.png" alt="enter image description here"></a></p>
  
  <p>The text must be in centre to the background view, even the count is in two digit numbers.For example count 55. I tried this using SCNText and SCNPlane, but didn't get good results. How can we achieve this in SceneKit?</p>
