%description
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.
