title: Anti-aliasing not working on Windows
body: <p>I'm working on a GLUT based app that needs to run on Windows XP, but as I'm on a Mac, I'm doing most of the coding in Xcode, then switching over to Visual C++ 2008 every once in a while to recompile. It's been working fine, but I just realized that anti-aliasing isn't working on the Windows version. </p>
  
  <p>Here are some screenshots:</p>

  <p>I'm using the GLUT display string "rgb alpha double samples depth". </p>
  
  <p>The shapes aren't actual 3D, they are just triangles:</p>
  
  <pre><code>glBegin(GL_TRIANGLES);
  {
      ofSetColor(edgeColorFar1.r, edgeColorFar1.g, edgeColorFar1.b);
      glVertex2f(CENTER_X, CENTER_Y);
      ofSetColor(edgeColorNear1.r, edgeColorNear1.g, edgeColorNear1.b);
      glVertex2f(x - _dim, y - _dim);
      glVertex2f(x + _dim, y - _dim);
  }
  glEnd();
  </code></pre>
  
  <p>Any ideas? Thanks!</p>
