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.

4342 * - If two chars or more are pressed in quick succession we search
4343 * for the corresponding string (e.g. 'abc').
4344 * - If there is a delay we wipe away the current search string and
4345 * restart with just that char.
4346 * - If the user keeps pressing the same character, whether slowly or
4347 * fast, so that the search string is entirely composed of this
4348 * character ('aaaaa' for instance), then we search for first item
4349 * that starting with that character.
4350 * - If the user types the above character in quick succession, then
4351 * we must also search for the corresponding string ('aaaaa'), and
4352 * go to that string if there is a match.
4360 * - The current implementation has a list of characters it will
4361 * accept and it ignores everything else. In particular it will
4362 * ignore accentuated characters which seems to match what
4363 * Windows does. But I'm not sure it makes sense to follow
4365 * - We don't sound a beep when the search fails.
4366 * - The search should start from the focused item, not from the selected
4367 * item. One reason for this is to allow for multiple selections in trees.
4368 * But currently infoPtr->focusedItem does not seem very usable.
