   paper with nice algorithm: http://citeseer.ist.psu.edu/cache/papers/cs/25021/http:zSzzSzfractal.dam.fmph.uniba.skzSz~sccgzSzproceedingszSz1998zSzZalik.pdf/zalik98quick.pdf
20121024 Request by Rick Rutgers: widening polygon contour

version 1.03: Tue Jan 21 14:33:07 CET 2014
	Changes:
	- add example to centroid, suggested by [Michael R. Davis]
	- change documentation style.

version 1.02: Mon Sep 19 12:06:32 CEST 2011
	- Added centroid functions, implemented by [Fred Zellinger]

version 1.01: Mon May 25 14:35:26 CEST 2009

	- Added Math::Polygon::Convex with chainHull_2D implementation by
	  [Jari Turkia] with many improvements.  Tests in t/50chainhull.t

	- do not run t/pod.t in devel environment.

version 1.00: Fri Feb  1 15:32:20 CET 2008

	- ::Calc::polygon_is_open() will die on empty polygon

	- correct ::Calc::polygon_contains_point() for point on vertical
	  edge. Spotted by [Rino Ingenito]

version 0.99: Fri Jun  8 16:31:33 CEST 2007

	- fillClip1() did not handle empty result connectly, neither
	  did ::Clip::polygon_fill_clip1().  Reported by [Christian Sauer]

	- added t/pod.t

version 0.98: Tue Apr  3 09:38:57 CEST 2007

	- missing export of polygon_is_closed [Christian Sauer]

version 0.97: Thu Mar 29 08:48:14 CEST 2007

	- fix prototype of polygon_rotate, to fix method rotate()
	  [Christian Sauer]

version 0.96: Fri Mar  9 14:19:41 CET 2007

	- refer to webpage http://perl.overmeer.net/geo

	- email address geo@overmeer.net

	- removed stuff to create own manual-pages.

	- all error messages should start with lower-case

version 0.95: Mon Feb 26 11:23:44 CET 2007

	- polygon_contains_point() only work if poly is closed: croak
	  otherwise. [Dennis Hartigan-O'Connor]

	- polygon_is_clockwise() will also croak when the poly is not
	  closed.

	- new polygon_is_closed() and $poly->isClosed.

	- use oodist to generate manuals, not own scripts.

	- bumped version number to indicate that the module interface
	  is stable: no major changes expected before 1.00

version 0.004: Fri Jul 21 10:17:44 CEST 2006

	- simplify() could get in an endless loop.

	- doc updates to fit into Geo::Point doc-set.

	- ring detection failed in Calc::polygon_start_minxy(), reported
	  by [mtworek]

version 0.003: Fri Dec  3 13:20:37 CET 2004

	- simplify will average close points.  Before, points could get
	  removed one after the other, until points over a long distance
	  were stripped.  That will not happen anymore.

	- polygon_start_minxy/Math::Polygon::startMinXY now returns the
	  point most close to (xmin,ymin) of the bounding box first. Was
	  the point with the smallest x.

	- new method Math::Polygon::contains(point) and function
	  Math::Polygon::Calc::polygon_contains_point(point, @poly)
	  with tests in t/14contains.t

version 0.002: Fri Nov 12 16:05:18 CET 2004

	- Created Math::Polygon::Transform, and added loads of test for it

	- Math::Polygon added interface to transform routines

version 0.001: Wed Sep  1 17:45:51 CEST 2004

	- Initial version
