2D vector drawing library for wxPython

[Basil Shubin]

Hi folks,

I am currently start a free software project called GFig (A better XFig 
than XFig :-)). As I am newbie free software developer (sounds cool, 
is't it? ;-)), so I like to ask: is there somewere a realy good 2D 
vector drawing library for wxPython? I just found a wxart2d project that 
looks good, but it is not for wxPython only wxWidgets and C++ is 
supported :-( And it seems not updated long ago...
Next question is how to implement a on-canvas ruler? What I shall use 
for making it? Make it as custom widget or maybe there any other solution?
And is there any other 2D drawing app or demos written with wxPython, so 
I can use it as example/tutorial?

Thank in advance and hope on yours help!
