title: Constant CENTER couldn't be resolved for rectMode() in Processing
body: <pre><code>public void show(PGraphics pg, float x, float y)
  {
      pg.rectMode(CENTER);
  
  }
  </code></pre>
  
  <p>I'm calling <code>rectMode</code> with the parameter <code>CENTER</code>, which should be a constant of type <code>int</code> according to the <a href="http://processing.org/reference/javadoc/core/processing/core/PGraphics.html#rectMode-int-" rel="nofollow">docs</a>, but <code>CENTER</code> couldn't be resolved.</p>
  
  <p>Moreover, <code>META-INF/MANIFEST.MF</code> of the <code>processing.core</code> jar doesn't specify its version.</p>
