+
+wxTreeItemData is some (arbitrary) user class associated with some item. The
+main advantage of having this class (compared to the old untyped interface) is
+that wxTreeItemData's are destroyed automatically by the tree and, as this
+class has virtual dtor, it means that the memory will be automatically
+freed. We don't just use wxObject instead of wxTreeItemData because
+the size of this class is critical: in any real application, each tree leaf
+will have wxTreeItemData associated with it and number of leaves may be
+quite big.
+
+Because the objects of this class are deleted by the tree, they should
+always be allocated on the heap.
