title: Not able to get updated mouse position without clicking
body: <p>I'm making a simple game using Pygame. I have embedded the the Pygame display into a Tkinter window.</p>
  <p>Now, when I execute this - <code>print(pygame.mouse.get_pos())</code> It does print the position, but when I move the mouse it doesn't print the updated mouse position. It still prints the previous mouse position unless I click on the display.</p>
  <p>This didn't happen with the same program before embedding the Pygame display into a Tkinter window.
  So, the event system doesn't seem to work properly.</p>
  <p>Someone suggested that, you could detect the events in Tkinter and then forward them to Pygame. But, I'm not sure how I'm going to implement that.</p>
  <p>How do I go about this? I would really appreciate some help here. Thank You!</p>
