title: Orthogonal projection to perspective projection MCP
body: <p>I am trying to code a mod for "Minecraft". I used the method "setupOverlayRendering" that changed the projection to orthogonal. I did this because I need to render text on screen. While the text is rendering I need to render a line, using perspective projection.</p>
  
  <pre><code>                    GL11.glMatrixMode(GL11.GL_PROJECTION);
                      GL11.glLoadIdentity();
                      GL11.glMatrixMode(GL11.GL_MODELVIEW);
                      GL11.glLoadIdentity();
  </code></pre>
  
  <p>I am using this code to revert the projection to perspective.</p>
