    Clear the VirtualDevice we create for an impBufferDevice on iOS
    
    Helps rendering of complex SmartArt with shapes a lot, especially such
    that include shadows. Exact mechanism unknown. Possibly on other
    platforms virtual devices get implicitly "cleared" when created? Sigh,
    fun.
    
    SmartArt is still not rendered fully like on desktop (OS X), though.
