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

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

33 * missing styles: TVS_FULLROWSELECT, TVS_INFOTIP, TVS_RTLREADING,
36 * missing item styles: TVIS_CUT, TVIS_EXPANDPARTIAL
38 * Make the insertion mark look right.
39 * Scroll (instead of repaint) as much as possible.

4144 * - If two chars or more are pressed in quick succession we search
4145 * for the corresponding string (e.g. 'abc').
4146 * - If there is a delay we wipe away the current search string and
4147 * restart with just that char.
4148 * - If the user keeps pressing the same character, whether slowly or
4149 * fast, so that the search string is entirely composed of this
4150 * character ('aaaaa' for instance), then we search for first item
4151 * that starting with that character.
4152 * - If the user types the above character in quick succession, then
4153 * we must also search for the corresponding string ('aaaaa'), and
4154 * go to that string if there is a match.
4162 * - The current implementation has a list of characters it will
4163 * accept and it ignores averything else. In particular it will
4164 * ignore accentuated characters which seems to match what
4165 * Windows does. But I'm not sure it makes sense to follow
4167 * - We don't sound a beep when the search fails.
4168 * - The search should start from the focused item, not from the selected
4169 * item. One reason for this is to allow for multiple selections in trees.
4170 * But currently infoPtr->focusedItem does not seem very usable.
