title: OpenGL ES iPhone - drawing anti aliased lines
body: <p>Normally, you'd use something like:</p>
  
  <pre><code>glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
  glEnable(GL_BLEND);
  glEnable(GL_LINE_SMOOTH);
  
  glLineWidth(2.0f);
  
  glVertexPointer(2, GL_FLOAT, 0, points);
  glEnableClientState(GL_VERTEX_ARRAY);
  
  glDrawArrays(GL_LINE_STRIP, 0, num_points);
  
  glDisableClientState(GL_VERTEX_ARRAY);
  </code></pre>
  
  <p>It looks good in the iPhone simulator, but on the iPhone the lines get extremely thin and w/o any anti aliasing.</p>
  
  <p>How do you get AA on iPhone?</p>
