title: PyGame, making the window move without the top bar
body: <p>I understand that you can set the initial position of the PyGame window with:</p>
  <pre><code>x,y = 100,50
  os.environ['SDL_VIDEO_WINDOW_POS'] = &quot;%d,%d&quot; % (x,y)
  </code></pre>
  <p>However, I would like to move the window while the code is running.</p>
  <p>Is there any simple way to do this that I missed in the documentation?</p>
