wxWidgets/include/wx/gdicmn.h
Vadim Zeitlin 89b799cccf Add wxSize::IncBy() and DecBy() overloads taking wxPoint. 
It seems to make at least as much sense to extend a wxSize by wxPoint than by
another wxSize (which doesn't make much size to me...) so add Inc/DecBy()
overloads doing this.

We might also add operator+=() overloads taking wxPoint for consistency but
for now don't add more operator overloads unnecessarily, let's wait if anybody
asks about this first.

/* 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.
