    tdf#119302 WIN better font scale handling
    
    Moves the scale factor into the LogicalFontInstance and uses the
    Glyphs font fallback level to use the correct font and scale.
    
    Probably the glyphs should be using a rtl::Reference to the
    LogcalFontInstance instead of the fallback level. I don't know if
    glyphs are evicted from the cache, if the fallback changes. There
    is now an assert and all places will use 1.0 as the default
    scaling factor, so LO should at least not crash.
