perl-Math-ConvexHull-MonotoneChain

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