title: Rotate a vertical rectangle to an horizontal one with Python Kivy - How?
body: <p>I'm trying to program a game with Python Kivy, only get stuck on one thing, will be a simple question, but I have not found a solution anywhere.</p>
  <p>I want the line in the middle of the screen (see picture attached) to be horizontal instead of vertical, meaning from left to right. Is there any method to rotate this? Or what do I have to change in the script?</p>

  <p>Here is my script that creates the graphic:</p>
  <pre><code>&lt;PongGame&gt;:
      canvas:
         Rectangle:
            pos:    self.center_x - 5, 0
            size: 10, self.height
  </code></pre>
  <p>I would appreciate any help. Keep in mind, I'm still pretty much a beginner.</p>
  <p>Best regards,</p>
