Represents an unsupported shape which has been loaded from a workbook file.
This class is used for round-tripping purposes, so unsupported shapes which have been loaded can be saved back out with the workbook. The class allows the unsupported shapes to be identified in shape collections so they can be removed. This shape will become obsolete in future versions when all shape types are supported.
