    n#773515 SwPageFrm::PaintBorderAndShadow fix shadow color on partial redraw
    
    How to reproduce: if you have a paragraph of text, and hit Enter in the
    middle of the paragraph, the frame around the document below the cursor
    position gets darker. Regression from
    f23d055dbee887ef9ebdf0a72b83ee1de91b7b8b.
