title: Add panel under screenshot
body: <p>I have a problem with adding description to screenshot. I capture camera screen like this: </p>
  
  <pre><code>    RenderTexture texture = new RenderTexture(Screen.width, Screen.height, 32);
      Camera.main.targetTexture = texture;
      RenderTexture.active = texture;
      Camera.main.Render();
      Texture2D texture2D = new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);
      texture2D.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
      texture2D.Apply();
  </code></pre>
  
  <p>Now I'm trying to add white panel with labels under captured screen and then save it to file. And now I have a problem. I don't know how to merge panel with image. I tried to add panel on canvas and then use <strong>Application.CaptureScreenshot();</strong> but it doesn't work as I want. The panel appears on the screenshot but cover some elements. How can I put panel under the screenshot? </p>
  
  <p>Thank you for your help!</p>
