When viewing a VW landscape generated Postscript file using Ghostview the document is presented upside-down. (I think the same problem occures when the file is printed on paper, but that's hard to prove :-)). Ghostview has features to rotate the document, but when exporting to pdf the same problem occures in Acrobat Reader. Acrobat Reader also has features to rotate the document.....
The following code change fixes the problem and rotates the postscript output the other way.
