11	* TODO:
12	* Using DPA to store the item ptr would be good.
13	* Node label edition is implemented but something appened in wine in the
14	* two last weeks of march 99 that broke it.
15	* refreshtreeview:
16	-small array containing info about positions.
17	-better implementation of RefreshItem:
18	1) draw lines between parents
19	2) draw items
20	3) draw lines from parent<->items.
21	-implement partial drawing?
22	* -drag&drop: TVM_CREATEDRAGIMAGE should create drag bitmap.
23	* -scrollbars: horizontal scrollbar doesn't work.
24	* -Unicode messages
25	* -check custom draw
26	* -I_CHILDRENCALLBACK
27	* FIXME: check fontsize. (uRealItemHeight)
28	* test focusItem (redraw in different color)
29	uHotItem
30	Edit: needs timer
31	better implementation.
32	* WM_HSCROLL is broken.
33	* use separate routine to get item text/image.
34	*
35	* Separate drawing/calculation.
36	*
37	* FIXMEs (for personal use)
38	Expand: -ctlmacro expands twice ->toggle.
39	-DblClick: ctlmacro.exe's NM_DBLCLK seems to go wrong (returns FALSE).
40	-treehelper: stack corruption makes big window.
