PLConsol() - polylist consolidator.
Geom *PLConsol(Geom *g, float prec);
PLConsol() is a function which takes a geom, which must be a polylist, as its
argument and returns a version of the polylist which has no repeated vertices.
Two vertices are considered to be identical if they are within prec of one
another. The comparison takes into account only the location of the points,
not their normals or colors.
The vertices of the resultant polyline have been sorted, and so
there order bears no resemblance to the order of the point in the original
PLConsol() is part of the geomutil library; see geomutil(3) for information on
how to link your program with this library.
