Comment (by nthiery):
Uploaded a new version (double checked by Travis) fixing one of the long
doctest failure on 5.10. It was caused by the new matplotlib that emits a
warning for arrows of length 0:
{{{
sage: arrow([1,1],[1,1])
/home/nthiery/sage-5.10.beta1/local/lib/python2.7/site-
packages/matplotlib/patches.py:3039: RuntimeWarning: invalid value

ddx = pad_projected * dx / cp_distance

}}}
The other failure is due to some doctests being ignored. See:
