title: How to enable antialiasing while using EffectComposer
body: <p>When using the EffectComposer from three.js it seems that the native antialiasing gets lost. The renderer is set with antialiasing: true; however, the result is full of janky edges.</p>
  
  <p>I tried to reduce the aliasing using the FXAA shader but it just doesn't have the quality that native antialiasing provides.</p>
  
  <p>Can somebody please suggest a solution?</p>
