/*
 * the class DS_DATA_ITEM (and derived) defines
 * a basic shape of a page layout ( frame references and title block )
 * Basic shapes are line, rect and texts
 * the DS_DATA_ITEM coordinates units is the mm, and are relative to
 * one of 4 page corners.
 *
 * These items cannot be drawn or plot "as this". they should be converted
 * to a "draw list" (DS_DRAW_ITEM_BASE and derived items)

 * The list of these items is stored in a DS_DATA_MODEL instance.
 *
 * When building the draw list:
 * the DS_DATA_MODEL is used to create a DS_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 DS_DATA_MODEL is created only once.
 * the DS_DRAW_ITEM_LIST is created each time the page layout is plot/drawn
 *
 * the DS_DATA_MODEL instance is created from a S expression which
 * describes the page layout (can be the default page layout or a custom file).
