27 * If item's text == LPSTR_TEXTCALLBACKA we allocate buffer

29 * We use callbackMask to keep track of fields to be updated.
32 * missing notifications: NM_SETCURSOR, TVN_GETINFOTIP, TVN_KEYDOWN,

35 * missing styles: TVS_FULLROWSELECT, TVS_INFOTIP, TVS_RTLREADING,
37 * missing item styles: TVIS_CUT, TVIS_EXPANDPARTIAL
39 * Make the insertion mark look right.
