           Summary: [GTK][AC] GraphicsLayerClutter doesn't need to
                    recalculate its position after changsing anchor
                    position.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kevin.cs.oh at gmail.com


Nothing drawn after replacing clutter_actor_set_anchor_point with clutter_actor_set_pivot_point.
The main reason is position of graphicsLayer.
As I mentioned in bug109037, clutter has a different coordinate system from mac port's, so I think we don't need to recalulate the position after changing anchor position.
