+// Problem:
+// The MSW version had problems with SetTextColour() et

+// 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

+// structure which contains the attributes we want *and*
