test failing on master

[pelson]

I am getting a test failure on the test_axes module, namely on test_contour_hatching.

pelson@~/dev/matplotlib> python tests.py matplotlib.tests.test_axes:test_contour_hatching
FFF

I've not yet had a chance to look into this issue further.

The range of colors present in the test is wider (both lighter and darker) than in the baseline image.

git bisect traced it back to this change 44d7556, which certainly makes sense.

@efiring: Assuming you stand by that change and extended range of colors is to be expected, then I suggest we update the baseline images for this example (to make the tests pass again) and maybe add a changelog entry that the range of colors selected from a colormap is now more inclusive/correct etc.?

I am working on a related change to color mapping in contours, so I can take care of this at the same time.
