          <para>To reduce <link
          xlink:href="http://en.wikipedia.org/wiki/Aliasing">aliasing
          effects</link>, the output image is usually rendered at a higher resolution
          than the final image (<emphasis>supersampling</emphasis>). This factor controls how much larger this
          resolution is. A factor of 1 turns anti-aliasing off. Higher values
          lead to better quality.</para>
