Summary: graph.pos method seems broken

Initial Comment:
The attached code snippet works fine with PyX 0.7.1,
but fails with PyX 0.8.1:

------

Traceback (most recent call last):
  File "pyx_pos.py", line 19, in ?
    x,y = g.pos(x=0,y=0)
  File
"/usr/local/lib/python2.4/site-packages/pyx/graph/graph.py",
line 169, in pos
    return self.xpos + xaxis.convert(x)*self.width,
self.ypos + yaxis.convert(y)*self.height
  File
"/usr/local/lib/python2.4/site-packages/pyx/graph/axis/axis.py",
line 472, in convert
    assert self.canvas is not None, self.errorname
AssertionError: x

------

I believe the cause of this is that the syntax of the
method "convert" has changed in the file
graph/axis/axis.py, but the pos method in the file
graph/graph.py has not been updated to reflect this change.
