title: pyglet resolution of screen into variables
body: <p>is there any options how to get values <code>height</code> and <code>width</code> of screen into variables using pyglet? I am able to print it but not extract these values.</p>
  
  <pre><code>import pyglet
  
  platform = pyglet.window.get_platform()
  display = platform.get_default_display()
  screen = display.get_screens()
  </code></pre>
  
  <p>-></p>
  
  <pre><code>&gt;&gt;&gt; screen
  [XlibScreen(display=&lt;pyglet.canvas.xlib.XlibDisplay object at 0x7f4644cf0990&gt;, x=0, y=0, width=1366, height=768, xinerama=0)]
  &gt;&gt;&gt; 
  </code></pre>
  
  <p>Any idea? Thanks in advance.</p>
