* Listview control
*
* Copyright 1998, 1999 Eric Kohl
* Copyright 1999 Luc Tourangeau
* Copyright 2000 Jason Mawdsley
* Copyright 2001 Codeweavers Inc.
* Copyright 2002 Dimitrie O. Paun
*
* NOTES
* Listview control implementation.
*
* TODO:
* 1. No horizontal scrolling when header is larger than the client area.
* 2. Drawing optimizations.
* 3. Hot item handling.
*
* Notifications:
* LISTVIEW_Notify : most notifications from children (editbox and header)
*
* Data structure:
* LISTVIEW_SetItemCount : not completed for non OWNERDATA
*
* Advanced functionality:
* LISTVIEW_GetNumberOfWorkAreas : not implemented
* LISTVIEW_GetHotCursor : not implemented
* LISTVIEW_GetISearchString : not implemented
* LISTVIEW_GetBkImage : not implemented
* LISTVIEW_SetBkImage : not implemented
* LISTVIEW_GetColumnOrderArray : simple hack only
* LISTVIEW_SetColumnOrderArray : simple hack only
* LISTVIEW_Arrange : empty stub
* LISTVIEW_ApproximateViewRect : incomplete
* LISTVIEW_Scroll : not implemented
* LISTVIEW_Update : not completed
*
* Known differences in message stream from native control (not known if
* these differences cause problems):
* LVM_INSERTITEM issues LVM_SETITEMSTATE and LVM_SETITEM in certain cases.
* LVM_SETITEM does not always issue LVN_ITEMCHANGING/LVN_ITEMCHANGED.
* WM_PAINT does LVN_GETDISPINFO in item order 0->n, native does n->0.
* WM_SETREDRAW(True) native does LVN_GETDISPINFO for all items and
* does *not* invoke DefWindowProc
* WM_CREATE does not issue WM_QUERYUISTATE and associated registry
* processing for "USEDOUBLECLICKTIME".

/*************************************************************************
* LISTVIEW_ProcessLetterKeys
*
* Processes keyboard messages generated by pressing the letter keys
* on the keyboard.
* What this does is perform a case insensitive search from the
* current position with the following quirks:
* - If two chars or more are pressed in quick succession we search
* for the corresponding string (e.g. 'abc').
* - If there is a delay we wipe away the current search string and
* restart with just that char.
* - If the user keeps pressing the same character, whether slowly or
* fast, so that the search string is entirely composed of this
* character ('aaaaa' for instance), then we search for first item
* that starting with that character.
* - If the user types the above character in quick succession, then
* we must also search for the corresponding string ('aaaaa'), and
* go to that string if there is a match.
*
* RETURNS
*
* Zero.
*
* BUGS
*
* - The current implementation has a list of characters it will
* accept and it ignores averything else. In particular it will
* ignore accentuated characters which seems to match what
* Windows does. But I'm not sure it makes sense to follow
* Windows there.
* - We don't sound a beep when the search fails.
