Reviewed by Dave Hyatt https://bugs.webkit.org/show_bug.cgi?id=24137 Fix localToAbsolute() and absoluteToLocal() to map points through 3d transforms, taking perspective and transform-style: preserve-3d into account. In order to support transform-style: preserve-3d, which keeps elements in a 3d space, we have to carry along an accumulated matrix in TransformState. We also need to apply the perspective from the parent, if any, with the appropriate origin. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@41208 268f45cc-cd09-0410-ab3c-d52691b4dbfc
