[pygtk] Display PostScript files in PyGTK without conversion?

[Kevin Milner]

Hello all, I am working on some geodynamics calculation/visualization 
software in python and am about to create a GUI. I like PyGTK so far, 
and would prefer to use it in our software, however I would need a way 
to display PostScript files. Obviously I could convert them to another 
format and use the Image widget, but I was wondering if there is a way 
to do it without this conversion (as the PostScript files will be 
updated frequently during use of the software). I have heard that there 
is a way to do this in QT, but would prefer to use GTK (through PyGTK). 
Thank you very much!
