Hi,
I fixed some of the contains() methods so at least the simple
cases work.
Degenerate rectangles cause problems in axes_demo:
import matplotlib.patches
r = matplotlib.patches.Rectangle((0,0),1,0)
r.get_transform().inverted()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/transforms.py", line 1338, in inverted
self._inverted = Affine2D(inv(mtx))
File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/numpy-1.1.0-py2.5-macosx-10.3-fat.egg/numpy/linalg/linalg.py", line 332, in inv
return wrap(solve(a, identity(a.shape[0], dtype=a.dtype)))
File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/numpy-1.1.0-py2.5-macosx-10.3-fat.egg/numpy/linalg/linalg.py", line 235, in solve
raise LinAlgError, 'Singular matrix'
numpy.linalg.linalg.LinAlgError: Singular matrix
I've only gone through the a*.py samples, but there are a few other glitches
such as not detecting axhline/axvline, not handling rotated text properly,
and not doing very well on polar plots. These will have to wait for another
release.

I see how this works with your example code, but how does this relate to axes_demo.py? I suppose the contains method will have to check for a singular matrix and just return False.

Agreed. Though if you can believe it, things are much better than they once were, particularly for polygons.
Cheers,
Mike
