Rich Graphics?

[Chris Spencer]

I'm trying to write a Gui in Python for manipulating rich graphical 
representations, similar to something like Inkscape. I've tried tkinter, 
wxPython, pyGtk, and while they all do traditional widgets well enough, 
none of them really handle anti-aliased, transparent, transformed shapes 
typical of vector based displays. I've noticed tkZinc, which seems to 
better handle vector graphics through the use of openGL, but it's 
traditional widget set is still limited and based on tkinter. Ideally, 
what I'm looking for is something like wxWidgets which can display SVG 
along side standard widgets and allow there manipulation through Python. 
I was thinking of a web-based route, by accessing the SVG capabilities 
in Mozilla's Deer Park browser through Twisted+Livepage, but this has 
been extremely complicated and limiting. Are there any other options I 
haven't considered?

Sincerely,
Chris
