/* Stock objects

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