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