    Fraction fiasco: avoid assert on clicking "master pages" in impress sidebar
    
    avoids the dread assert in vcl wrt. "detect overflows" in ImplLogicToPixel of
    vcl/source/outdev/map.cxx but the whole thing looks a nightmare if a high
    precision double is given as an arg to Fraction and the underlying boost foo
    uses longs longer than 32bits to represent that.
