title: SDL multisampling and OpenGL
body: <p>To enable multisampling I am using the following code in my project:</p>
  
  <pre><code>SDL_GL_SetAttribute(SDL_GL_MULTISAMPLEBUFFERS, 1);
  SDL_GL_SetAttribute(SDL_GL_MULTISAMPLESAMPLES, 4);
  </code></pre>
  
  <p>Do I also need to call <code>glEnable(GL_MULTISAMPLE);</code>?</p>
  
  <p>I see no difference if I don't call it.</p>
