title: Switch GLFW windows for key presses
body: <p>I have two GLFW windows, and I would like to be able to switch between them and then move the camera around using the keyboard.</p>
  
  <p>Currently: </p>
  
  <ul>
  <li>I can switch between rendering in window 1 and window 2 by using glfwGetCurrentContext</li>
  <li>BUT when I switch between the windows, the new window isn't the front window. As a result, none of the keypresses register until I click on the new window. </li>
  </ul>
  
  <p><strong>Question:</strong> How do I make the new window automatically come to the front so I don't have to manually click on the window.</p>
