FYI, the purpose of the original paper[1] that GQ_Detail is based upon had
an elegant algorithm for creating convex hulls. However, I'm not sure if
GQ_Detail implemented enough of it to simply use the algorithm mentioned
in the paper (it might).


1. The paper reference can be found in GQ_Detail.h.
