%description
This is somewhat experimental still.

This (XS) module optionally exports a single function convex_hull
which calculates the convex hull of the input points and returns it.
The algorithm is O(n log n) due to having to sort the input list, but
should be somewhat faster than a plain Graham's scan (also O(n log n))
in practice since it avoids polar coordinates.
