title: glPolygonOffset() bugs with lines
body: <p>I have the following code:</p>
  
  <pre><code>glEnable(GL_POLYGON_OFFSET_LINE);
  glPolygonOffset(1,1); // or 40,40 etc... doesnt help at all
  </code></pre>
  
  <p>But the lines are still z-fighting, is this common bug or something...? My lines are 1.0f thick and i draw the lines last in the scene.</p>
  
  <p>Also i have disable GL_ALPHA_TEST and GL_LINE_SMOOTH and enabled GL_BLEND and GL_COLOR_LOGIC_OP</p>
  
  <p><strong>Edit:</strong> i have already tried GL_POLYGON_OFFSET_FILL, it doesnt help.</p>
