+ * the class WORKSHEET_DATAITEM (and WORKSHEET_DATAITEM_TEXT) defines
+ * a basic shape of a page layout ( frame references and title block )
+ * Basic shapes are line, rect and texts
+ * the WORKSHEET_DATAITEM 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" (WS_DRAW_ITEM_BASE and derived items)
+
+ * The list of these items is stored in a WORKSHEET_LAYOUT instance.
+ *
+ * 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 plotted/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).
