/*
* The WS_DATA_ITEM_* classes define the basic shapes of a drawing sheet (frame references
* and title block). The list of these items is stored in a DS_DATA_MODEL instance.
*
* These items cannot be drawn or plotted "as is". They must be converted to WS_DRAW_*
* types. 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 WS_DRAW_ITEM_*s are created and maintained by the PlEditor, but are created each time
* they're needed for drawing by the clients (Eeschema, Pcbnew, etc.)
*
* The DS_DATA_MODEL instance is created from a S expression which describes the drawing sheet
* (can be the default drawing sheet or a custom file). This format is also used for undo/redo
* storage (wrapped in a DS_PROXY_UNDO_ITEM).
