Description Ryosuke Niwa 2013-10-10 19:50:21 PDT

Once https://bugs.webkit.org/show_bug.cgi?id=122631 is fixed, we should collapse all subclasses of EventContent into EventContent.
This will allow stack allocation of EventPath in most cases (when the path is less than 32 nodes) and paves our way to get rid of EventContext entirely.
