[mkgmap-dev] Commit r3679: overview_levels_v3.patch

Version mkgmap-r3679 was committed by gerd on Wed, 20 Jul 2016 overview_levels_v3.patch Fix possible problems with 0x4a polygons in the overview map when tiles with different levels are merged into one map The old code used only the first processed tile to calculate the level 0 resolution for the overview map. The patched version collects all 0x4a tiles and - if needed - reduces the resolution so that the largest tike can be written without problems. http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=3679
