40 // all XShapes/SdrObjects of an already imported Diagram. The
41 // Diagram holds the SmarArt model data before it gets layouted,
42 // while Theme holds the oox Fill/Line/Style definitions to
43 // apply.
44 // Re-Layouting (re-creating) is rather complex, for detailed
45 // information see ::reLayout implementation.
46 // This helper class may/should be extended to:
47 // - deliver representative data from the Diagram-Model
48 // - modify it eventually
49 // - im/export Diagram model to other representations
