*
* 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
*
* Unicode:
* LISTVIEW_SetItemW : no unicode support
* LISTVIEW_InsertItemW : no unicode support
* LISTVIEW_InsertColumnW : no unicode support
* LISTVIEW_GetColumnW : no unicode support
* LISTVIEW_SetColumnW : no unicode support
*
* Advanced functionality:
* LISTVIEW_GetNumberOfWorkAreas : not implemented
* LISTVIEW_GetHotCursor : not implemented
* LISTVIEW_GetISearchString : not implemented
* LISTVIEW_GetBkImage : not implemented
* LISTVIEW_GetColumnOrderArray : simple hack only
* LISTVIEW_SetColumnOrderArray : simple hack only
* LISTVIEW_Arrange : empty stub
* LISTVIEW_ApproximateViewRect : incomplete
