wxWidgets/include/wx/gdicmn.h
Vadim Zeitlin 06cfc05269 Add wxPoint::IsFullySpecified() and SetDefaults(). 
These methods do the same thing as wxSize methods with the same names and are
useful for the same reasons.

/* 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. Platorm-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.
