commit 8ad9d0a22d44f5bcd183673ef48e8e0eb7cfed92

    Bug 644242 - Register Panning Problem
    
    If the horizontal scrollbar is present for a register and you start to
    tab from one cell to the next one that is not in view the sheet does
    not scroll to keep the active cell in view.
    
    This commit fixes that by getting the active cell horizontal offset and
    width and comparing it to the sheet width and window width.
