        <pre>Lot of CSS3 blending tests fail. The failure is obvious if you compare the pixel test images generated on WebKitGTK+ vs Mac port.

Possible cause: we are not enabling CSS_COMPOSITING.

Mac port enabled it a lot of time ago: <a href="https://trac.webkit.org/r130460">https://trac.webkit.org/r130460</a>

Most of the css3/blending tests are currently skipped due to <a class="bz_bug_link 
          bz_status_UNCONFIRMED "
   title="UNCONFIRMED - [GTK] Move towards Xvfb-less testing"
