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