+ * Create Stencil that represents a filled polygon with round edges.
+ *
+ * LIMITATIONS:
+ *
+ * (a) Only outer (convex) edges are rounded.
+ *
+ * (b) This algorithm works as expected only for polygons whose edges
+ * do not intersect. For example, the polygon ((0, 0), (q, 0), (0,
+ * q), (q, q)) has an intersection at point (q/2, q/2) and therefore
+ * will give a strange result. Even non-adjacent edges that just
+ * touch each other will in general not work as expected for non-null
+ * blotdiameter.
+ *
+ * (c) Given a polygon ((x0, y0), (x1, y1), ... , (x (n-1), y (n-1))),
+ * if there is a natural number k such that blotdiameter is greater
+ * than the maximum of { | (x (k mod n), y (k mod n)) - (x ((k+1) mod n),
+ * y ((k+1) mod n)) |, | (x (k mod n), y (k mod n)) - (x ((k+2) mod n),
+ * y ((k+2) mod n)) |, | (x ((k+1) mod n), y ((k+1) mod n)) - (x ((k+2)
+ * mod n), y ((k+2) mod n)) | }, then the outline of the rounded
+ * polygon will exceed the outline of the core polygon. In other
+ * words: Do not draw rounded polygons that have a leg smaller or
+ * thinner than blotdiameter (or set blotdiameter to a sufficiently
+ * small value -- maybe even 0.0)!
+ *
+ * NOTE: Limitations (b) and (c) arise from the fact that round edges
+ * are made by moulding sharp edges to round ones rather than adding
+ * to a core filled polygon. For details of these two different
+ * approaches, see the thread upon the ledger lines patch that started
+ * on March 25, 2002 on the devel mailing list. The below version of
+ * round_filled_polygon () sticks to the moulding model, which the
+ * majority of the list participants finally voted for. This,
+ * however, results in the above limitations and a much increased
+ * complexity of the algorithm, since it has to compute a shrinked
+ * polygon -- which is not trivial define precisely and unambigously.
+ * With the other approach, one simply could move a circle of size
+ * blotdiameter along all edges of the polygon (which is what the
+ * postscript routine in the backend effectively does, but on the
+ * shrinked polygon). --jr
