title: Is SFML::View inverted-y axis standard? How to workaround it?
body: <p>I have my objects in a world space using right-handed coordinates (x = right, y = up).</p>
  
  <p>When I have to render them using SFML I'm having problems because I can't set up the View matrix in sf::View with a (y = up) matrix and then all is rendered y-flipped.</p>
  
  <p>One solution I'm thinking is flipping the y-axis on every object before rendering it: </p>
  
  <pre><code>ObjectTransformMatrix * MatrixScale(1.0f,-1.0f)
  </code></pre>
  
  <p>But I think I will have to move the sf::View center to:</p>
  
  <pre><code>y = y - (view_size.y / 2.0)
  </code></pre>
  
  <p>Why sf::View is y-inverted ? Is my solution correct? </p>
