Version mkgmap-r3682 was committed by gerd on Thu, 21 Jul 2016 Improve Filter to catch special cases where the closing point of a shape is part of a spike or lies on a straight line This will remove a few more obsolete points from shapes, but the effect on the img size is very small. http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=3682
