wxSF 1.2 released

wxShapeFramework v1.2.0 alpha has been released today. This release contains several new features and API functions and the main change (improvement, I hope :)) is that data and presentation layers have been separated. From now, the diagram items (shapes) are managed by wxSFDiagramManager class which is suitable for data serialization and examining of the digram structure, and the presentation layer allowing displaying and in-place modifying of diagram structure is provided by old wxSFShapeCanvas class. This approach is useful for cases when the diagram should be serialized or changed even if it is not displayed (shape canvas is no created yet).
