           Summary: [BlackBerry] Disable paintingGoesToWindow() for the
                    root layer when force compositing mode is active
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: anilsson at rim.com


The BlackBerry port will use accelerated compositing code path to render the root layer in some situation.

The plan is to do this by activating the forceCompositingMode() setting, but that in itself doesn't accomplish anything, since painting will still go to window for the root layer.

Thus a special clause in RenderLayerBacking::paintingGoesToWindow() will be added for PLATFORM(BLACKBERRY).
