 603   by the Item enum values.  Platorm-specific fonts can be created by
 604   implementing a derived class with an override for the GetFont function.
 605   wxStockGDI operates as a singleton, accessed through the ms_instance
 606   pointer.  By default this pointer is set to an instance of wxStockGDI.
 607   A derived class must arrange to set this pointer to an instance of itself.
