[mkgmap-dev] Commit r3736: Add check to avoid the processing of artifacts created by the split process.

Version mkgmap-r3736 was committed by gerd on Wed, 21 Dec 2016 Add check to avoid the processing of artifacts created by the split process. If option --order-by-decreasing-area is used shapes are split at suv division boundaries. This can create shapes with an area size very close to zero. These can be safely ignored at lower resolutions. http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=3736
