/*
 * the class WORKSHEET_DATAITEM (and derived ) defines
 * a basic shape of a page layout ( frame references and title block )
 * The list of these items is stored in a WORKSHEET_LAYOUT instance.
 *
 *
 * These items cannot be drawn or plot "as this". they should be converted
 * to a "draw list". When building the draw list:
 * the WORKSHEET_LAYOUT is used to create a WS_DRAW_ITEM_LIST
 *  coordinates are converted to draw/plot coordinates.
 *  texts are expanded if they contain format symbols.
 *  Items with m_RepeatCount > 1 are created m_RepeatCount times
 *
 * the WORKSHEET_LAYOUT is created only once.
 * the WS_DRAW_ITEM_LIST is created each time the page layout is plot/drawn
 *
 * the WORKSHEET_LAYOUT instance is created from a S expression which
 * describes the page layout (can be the default page layout or a custom file).
