[mkgmap-dev] Commit: r3333: merge branch rhumbline to fix issues with very long lines which are

Version mkgmap-r3333 was committed by gerd on Fri, 08 Aug 2014 merge branch rhumbline to fix issues with very long lines which are great circle paths like the "Great Britain National Grid". Since Garmin assumes that all line segments are rhumb lines, we have to make sure that we don't remove too many points from GC lines. The advantage is that this reduces the number of needed complex bearing calculation a little bit.
