    tdf#103927: Share single standard VirtualDevice instance.
    
    To avoid creating excessive amounts of VirtualDevice instances. Also,
    since we now have VclPtr, we shouldn't need this bOwnerOfRefDev flag.
    
    This fixes tdf#102688 as well as other GDI-Limit related issues.
    
    See tdf#105469 for other bugs this may fix.
    
    (cherry picked from commit b41186a2fc49e440890b8c86e5367352ffaf9cd6)
