11 * TODO:
12 * Using DPA to store the item ptr would be good.
13 * -check custom draw
14 * use separate routine to get item text/image.
15 *
16 * FIXMEs (for personal use)
17 Expand: -ctlmacro expands twice ->toggle.
18 -DblClick: ctlmacro.exe's NM_DBLCLK seems to go wrong (returns FALSE).
19 -treehelper: stack corruption makes big window.

21 * Status: complete (many things untested)
