This is the issue that Fred Wolfe and I batted back 
and forth, although some of the discussion was 
guessing in the dark before -gs_fileinfo- was remembered. 

The key point as I understand it is that the command Stata's graph 
internals received, which was not what you typed, is to be 
interpreted with reference to the serset associated with the graph.
