+ All this is quite ugly but serves two purposes:
+ 1. Be almost 100% compatible with old, untyped, wxList class
+ 2. Ensure compile-time type checking for the linked lists
+
+ The idea is to have one base class (wxListBase) working with "void *" data,
+ but to hide these untyped functions - i.e. make them protected, so they
+ can only be used from derived classes which have inline member functions
+ working with right types. This achieves the 2nd goal. As for the first one,
+ we provide a special derivation of wxListBase called wxList which looks just
+ like the old class.
