*
* TODO:
* - Nearly all notifications.
*
* list-handling stuff: sort, sorted insertitem.
*
* refreshtreeview:
-small array containing info about positions.
-better implementation of DrawItem (connecting lines).
-implement partial drawing?
* Expand: -ctlmacro expands twice ->toggle.
* -drag&drop.
* -scrollbars.
* -Unicode messages
* -TVITEMEX
*
* FIXMEs:
-GetNextItem: add flags for traversing child lists.
(DESCEND_ALWAYS, DESCEND_NEVER, DESCEND_VISIBLE)
-DblClick: ctlmacro.exe's NM_DBLCLK seems to go wrong (returns FALSE).
