[mkgmap-dev] [PATCH v4] make DP filter avoid removing points located at nodes

v4 - err, try again --------- v3 - hopefully, now works again after being broken by the round coords filter. --------- v2 - based on r1402. ----------- Hi Felix, Please try the attached patch. I've tested it inasmuch that it doesn't blow up but whether it actually does the right thing when you have a routable and non-routable way from the same set of points, I don't know. Cheers, Mark
