HYPOTHESIS (I have no time to check now everything..., I did my best.)reckoner:
>>> th= array([ 4.65542641, 5.32920696, 2.20928291])
>>> print p.contains_point((0,0))
>>> print matplotlib.nxutils.pnpoly(0,0,p.get_path().vertices)
I can confirm this for both the current development branch and v1.1.x. Strange....
