Included below. This doesn't do closed splines yet but they shouldn't
be too difficult to add. I hope the way I did it is not too horrible.

I probably have forgotten something - the important change is the
addition of the orig_coords and orig_numpoints fields which are
what the user gave - for non-smoothed lines, coords and numpoints are
assigned the same values, for smoothed ones, coords and numpoints are
generated.
