    tdf#71603: Create a new DC for the font fallback
    
    For some reason re-using the DC from SalGraphics results in
    GetFontData() returning GDI_ERROR and we fail to read the font’s 
“cmap”
    table. The wired thing is that this happens only for fonts that were
    not used before, so if you open a document directly the fallback works
    but if you open start center or blank Writer document you get no
    fallback. GDI is “interesting”.
