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