title: Anti-aliasing filled shapes in libgdx
body: <p>I've been looking everywhere for a way to anti-alias edges of filled shapes drawn with <code>ShapeRenderer</code> (ie. <code>ShapeType.Filled</code>) but can't find anything about this. </p>
  
  <p>Lines works well with <code>Gdx.gl.glEnable(GL10.GL_LINE_SMOOTH)</code> but nothing I've tried works with filled shapes. So, does anyone have any suggestions?</p>
