/**
* The RtfShape provides the interface for adding shapes to
* the RTF document. This will only work for Word 97+, older
* Word versions are not supported by this class.<br /><br />
*
* Only very simple shapes are directly supported by the RtfShape.
* For more complex shapes you will have to read the RTF
* specification (iText follows the 1.6 specification) and add
* the desired properties via the RtfShapeProperty.<br /><br />
*
* One thing to keep in mind is that distances are not expressed
* in the standard iText point, but in EMU where 1 inch = 914400 EMU
* or 1 cm = 360000 EMU.
