           Summary: Move RenderObject's layer manipulation functions to
                    RenderLayer
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jchaffraix at webkit.org

Currently layer manipulation functions (addLayers, removeLayers...) are attached to RenderObject as they are called on any RenderObject and update its subtree, which may include some RenderBoxModelObject with RenderLayer (not reflected by the name unfortunately). However this artificially exposes RenderLayer on an object that shouldn't know about it.

All the layer's manipulation functions requires a RenderLayer and could thus be moved to RenderLayer.

Patch forthcoming.
