When I try to run this with matplotlib 1.1.0, I get:

Traceback (most recent call last):
   File 
"/Users/grout/sage-trees/sage-5.4.rc1/local/lib/python2.7/site-packages/tornado-2.4-py2.7.egg/tornado/web.py", 
line 1042, in _execute
     getattr(self, self.request.method.lower())(*args, **kwargs)
   File "/Users/grout/projects/matplotlib-live/serve_figure.py", line 
174, in get
     np.frombuffer(renderer.buffer_rgba(), dtype=np.uint32),
TypeError: buffer_rgba() takes exactly 3 arguments (1 given)

and the image doesn't show up.  Is this something that is fixed in an 
matplotlib upgrade?

Thanks,

Jason
