From: mike pitman <pitman@us.ibm.com>

fixes the terrain spikes, and is the result of mostly a tuning
operation on the smooth and flatten tools. I dug in and found that the
spikes apparently result from smooth's overly aggressive iteration
steps toward the average curvature, which leads to an instability that
blows up the heights. I introduced a scaling factor to dampen the
'duration' parameter which tames progress and seems to keep things
stable.
