691 wxStockGDI creates the stock GDI objects on demand. Pointers to the
692 created objects are stored in the ms_stockObject array, which is indexed
693 by the Item enum values. Platorm-specific fonts can be created by
694 implementing a derived class with an override for the GetFont function.
695 wxStockGDI operates as a singleton, accessed through the ms_instance
696 pointer. By default this pointer is set to an instance of wxStockGDI.
697 A derived class must arrange to set this pointer to an instance of itself.
