title: How to convert from (x, y) screen coordinates to LatLng (Google Maps)
body: <p>I am implementing an application using Google Maps and Leap Motion and what I want right now, and I am a bit stuck, is a way to convert (x, y) screen coordinates into a Google Maps LatLng object.</p>
  
  <p>I want to achieve this in order to start, for example, a panorama (Street View) at the point where the user is pointing with the Leap Motion.</p>
  
  <p>I know about the presence of fromPointToLatLng function, but I have no clue what is the right approach in using it and how can I translate my x and y coordinates into lat lng variables.</p>
  
  <p>Can you please help me with this? </p>
