title: Using GMaps API v3 with GEarth Plugin when GEarth Plugin isn't installed
body: <p>I've built a web application that runs on Google Maps API v3 and integrates the Google Earth API/Plugin to show my map in both 2D and 3D. As Google Maps API v3 doesn't have built-in support for the Google Earth Plugin, I'm using <a href="https://github.com/myshen/google-maps-v3-earth-map-type" rel="nofollow noreferrer">this library</a>.</p>
  
  <p>That library is working great, except that when I initialize my 2D and 3D maps, if the Google Earth plugin is not installed, I get a message like this across my entire map window, and I can't even use the 2D map:</p>
  
  <p><img src="https://i.imgur.com/9dUzF.png" alt="Problem"></p>
  
  <p><strong>Is there a way to disable this message or to hide it underneath my 2D map type?</strong> If not, is there some way to detect whether the Google Earth plugin is installed before loading and initializing the 3D library?</p>
