947   created objects are stored in the ms_stockObject array, which is indexed
948   by the Item enum values.  Platorm-specific fonts can be created by
949   implementing a derived class with an override for the GetFont function.
950   wxStockGDI operates as a singleton, accessed through the ms_instance
951   pointer.  By default this pointer is set to an instance of wxStockGDI.
952   A derived class must arrange to set this pointer to an instance of itself.
