Okay.  Here's an update for the skinner script.  I've managed to speed up the smoothing a bit, as well as establish conditions which will allow it to preserve vertex placement for vertices with particularly "sharp" angles, relative to their ring neighbors, which generally seem to represent a place where the vertices shouldn't move, lest polygon poke-through result.

I've deactivated the vertex-reordering, after having tested the smoothing without it.  The "bias" in the neck and head disappears if the reordering is off.  The smoothing alone seems to do a very good job of cleaning up the mesh.  The twisted polygons which have been a problem since the start are being fixed by the smoothing, so the results are pretty good.  Better than expected.

Next I'll be trying to force the seam positioning, as discussed above.
