   7  * TODO:
   8  *   list-handling stuff: sort, sorted insertitem.
   9  *           [should be merged with mm-handling stuff as done in listview]
  10  *   refreshtreeview:
  11                 -small array containing info about positions.
  12                 -better implementation of RefreshItem:
  13               1) draw lines between parents
  14               2) draw items
  15                           3) draw lines from parent<->items.
  16                 -implement partial drawing?
  17  *  -drag&drop: TVM_CREATEDRAGIMAGE should create drag bitmap.
  18  *  -scrollbars: horizontal scrollbar doesn't work.
  19  *  -Unicode messages
  20  *  -check custom draw
  21  *  -I_CHILDRENCALLBACK
  22  *   FIXME: check fontsize. (uRealItemHeight)
  23  *          test focusItem  (redraw in different color)
  24                         uHotItem
  25                         Edit: needs timer
  26                                   better implementation.
  27  *   WM_HSCROLL is broken.
  28  *   use separate routine to get item text/image.
  29  *
  30  *   Separate drawing/calculation.
  31  *
  32  * FIXMEs  (for personal use)
  33     Expand:             -ctlmacro expands twice ->toggle.
  34    -DblClick:   ctlmacro.exe's NM_DBLCLK seems to go wrong (returns FALSE).
  35    -treehelper: stack corruption makes big window.
