           Summary: [Qt] Repaint counter for accelerated compositing
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Keywords: Qt
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: noam.rosenthal at nokia.com


To debug graphics and performance, we want to enable web developers to see when a composited layer's content has been updated, as that is commonly a cause for choppiness.
The accelerated compositing abstraction already provides the hooks to do that, but we need to implement the Qt/TextureMapper specific parts of it.
