How to view DBDesigner4 documents in Mac OS X

Unfortunately, DBDesigner4 is written in Delphi, which is practically Windows-only, so there is not and probably will not be a Mac OS X version. Also, no other applications are able to show diagrams in this format. 
 DBDesigner is replaced by MySQL workbench. It was a part of the MySQL GUI Tools bundle until recently, when it was removed as it was too unstable. I have read somewhere that they are rewriting the application, so it would not be ready for a while. 
 Workarounds: 
 
 Open a diagram in DBDesigner4 in Windows, export the diagram to raster image ( PNG , etc), then view the exported image in OS X. 	 Use an emulator (e.g. Parallels, Wine, Darwine) to run DBDesigner4 on OS X.
