In <http://trac.webkit.org/changeset/66948> Path::closeCanvasSubpath() was added to fix around a problem that wasn't fully understood at the time. It turns out that the whole thing was a bug in Qt's SVG-compliant path stroker. It has been fixed for Qt 4.7.1 and we should remove the workaround kludge from WebKit.
