            Bug ID: 218529
           Summary: [GPU Process] Use the Ref counting of ImageBuffer to
                    control its life cycle in Web Process and GPU Process
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Canvas
          Assignee: webkit-unassigned at lists.webkit.org

DrawImageBuffer will hold a Variant<RefPtr<WebCore::ImageBuffer>, RenderingResourceIdentifier>. The RefPtr<WebCore::ImageBuffer> will be set in the Web Process when drawing an ImageBuffer to another ImageBuffer. The RenderingResourceIdentifier of ImageBuffer will be encoded when sending the DisplayList to the GPU Process. In the GPU process, a DrawImageBuffer will be decoded with RenderingResourceIdentifier. The RemoteRenderingBackend will search for the ImageBuffer in its RemoteResourceCache given the RenderingResourceIdentifier and will draw it to the GraphicsContext. This will remove the need to lock and unlock the remote resource in RemoteResourceCacheProxy.
