wxWidgets/include/wx/gdicmn.h
Vadim Zeitlin ded2894b78 Add wxDisplay::GetPPI() to use instead of wxGetDisplayPPI() 
While this is not done for all the ports yet, the new API allows
returning different PPI values for different monitors, unlike the old
(and still existing, but implemented in terms of the new one) global
function.

/* 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.
