//  RwColumnHeaderWidget is a Qt4 Horizontal QHeaderView implementation.
//  This widget maintains a character string (RWCString, ASCII) for each
//  column.
//
//  SUPPORTED FORMAT TYPES:
//     RwColumnHeaderWidget::FormatType
//
//        FMT_DEFAULT = 0    // default format, non-rotated text.
//        FMT_ROTATED_UP     // quarter-turn counter-clockwise [PREFERRED]
//        FMT_ROTATED_DOWN   // quarter-turn clockwise, like a book spine.
//
//  DEVELOPMENT STATUS [9-19-2008]:
//
//    Recently Completed:
//      o Column selection support (for full table column selection).
//      o Header section beveled border drawing.
//      o Selection ornamentation (full table column and single cell in col).
//      o Direct rotated text drawing (no longer using intermediate QPixmaps).
//
//    Not Completed *** NOT PLANNED for the current development [9-19-2008]:
//      o Column Sort Indicator (triangle arrow shown in sorted column).
//      o Support for multiple-line header text (either rotated or not).
//      o Text Alignment. All header text is centered in both dimensions.
//
