28  * The WS_DATA_ITEM_* classes define the basic shapes of a drawing sheet (frame references
29  * and title block). The list of these items is stored in a DS_DATA_MODEL instance.
30  *
31  * These items cannot be drawn or plotted "as is". They must be converted to WS_DRAW_*
32  * types. When building the draw list:
33  * - the DS_DATA_MODEL is used to create a DS_DRAW_ITEM_LIST
34  * - coordinates are converted to draw/plot coordinates.
35  * - texts are expanded if they contain format symbols.
36  * - items with m_RepeatCount > 1 are created m_RepeatCount times.
37  *
38  * The DS_DATA_MODEL is created only once.
39  * The WS_DRAW_ITEM_*s are created and maintained by the PlEditor, but are created each time
40  * they're needed for drawing by the clients (Eeschema, Pcbnew, etc.)
41  *
42  * The DS_DATA_MODEL instance is created from a S expression which describes the drawing sheet
43  * (can be the default drawing sheet or a custom file). This format is also used for undo/redo
44  * storage (wrapped in a DS_PROXY_UNDO_ITEM).
