+// Problem:
+// The MSW version had problems with SetTextColour() et
+// al as the wxListItemAttr's were stored keyed on the
+// item index. If a item was inserted anywhere but the end
+// of the list the the text attributes (colour etc) for
+// the following items were out of sync.
+//
+// Solution:
+// Under MSW the only way to associate data with a List
+// item independant of its position in the list is to
+// store a pointer to it in its lParam attribute. However
+// user programs are already using this (via the
+// SetItemData() GetItemData() calls).
+//
+// However what we can do is store a pointer to a
+// structure which contains the attributes we want *and*
+// a lParam for the users data, e.g.
+//
+// class wxListItemInternalData
+// {
+// public:

+//   long lParam; // user data
+// };
