Given that we're wrapping a C++ library, #2 is useless, since C++ has
the same explicit virtual semantics as C#.  As such, even if all methods
in C# were marked as virtual, the polymorphism properties wouldn't exist
within the C++ bindings.

I feel that if the wxWidgets designers chose to make something virtual
or not, that is the best way to go.
