According to geojson spec the coordinates of a feature can have 3 dimensions. Before this change the 3rd component of the geometry was misused to store the simplification values of the Douglas-Peucker algorithm. With this change the simplification values are stored in a separate array(sqDist) and the 3rd component of the coordinate remains untouched. Signed-off-by: Nino Kettlitz <[email protected]>
