    tdf#90604: vcl: reduce MapMode precision further to 32 bits...
    
    ... which mysteriously causes the Export PNG to produce a non-blank
    image again.
    
    The cause is probably that DocumentToGraphicRenderer::renderToGraphic()
    records a VCL MetaFile, and the ReadFraction/WriteFraction do only
    32 bits, while the Fraction interface promises to handle "long".
    
    (regression from 2ce0aededea43231d91a0955fc0676120dcc4f13)
