Comment(by fbissey):
I have trouble applying trac_10140_base_cone_on_ppl.patch. The following
section doesn't apply at least:
{{{
@@ -1578,7 +1667,7 @@
Let's take a 3-d cone on 4 rays::
- sage: c = Cone([(1,0,1), (0,1,1), (-1,0,1), (0,-1,1)])
+ sage: c = Cone([(1,0,1), (0,1,1), (-1,0,1), (0,-1,1)],
check=False)
Then any ray generates a 1-d face of this cone, but if you
construct
such a face directly, it will not "sit" inside the cone::
}}}
Is it due to #9972? I can see that particular section in #9972 but
slightly shifted in line number.
