Version 1406 was commited by markb on 2009-11-27 17:27:52 +0000 (Fri, 27 Nov 2009) 

Stop the DP filter from removing points that are located at nodes.

Until now, the DP filter would consider any point that isn't actually
a routing node fair game for removal. However, if two lines are generated
from the same set of points and one has nodes and the other doesn't, they
will end up different shapes which looks wrong. So now, the DP filter will
avoid removing any points that have been marked as "preserved".
