           Summary: Clean up scrollXOffset/addScrollOffset stuff on
                    RenderLayer
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: simon.fraser at apple.com


Bug 5826 added some code in RenderLayer that adds a m_scrollLeftOverflow member
variable for some RTL issues. So RL now has

scrollXOffset/scrollYOffset

and 

addScrollOffset/subtractScrollOffset (which got renamed via bug 21941).

Only the latter methods take m_scrollLeftOverflow into account, but hyatt
thinks that m_scrollLeftOverflow is always equal to -m_scrollX. This needs
cleaning up, with any special-case RTL stuff kept internal to RenderLayer.
