    tdf#91920 sw page gutter margin: add layout
    
    Handle this in general by decreasing the print area of the page frame,
    that way the position and size of the child frames (header, body, etc)
    will be correct.
    
    One catch is that the page border is independent from the gutter margin
    in Word, so compensate for it in lcl_CalcBorderRect() have matching
    render result. (E.g. 1cm gutter margin, 1cm left and right margins, then
    we would default to drawing the left margin at 2cm from left edge, but
    1cm is wanted.)
