Table_smooth smoothes only polylines and does it well, no doubt about it. But what is its usefulness for smoothing regions?
Of course if you have a single region, or well separated regions, you could convert them to polylines, smooth them and convert them back to regions, and you will get smoothed regions. But if you have a set of adjacent regions, forget it, you will obtain only a topological mess with gaps and overlaps. Corners with internal angles<180 are not filled, and if there is a corner in an adjacent region with internal angle > 180, the "added" area overlaps the rounded corner. Because of the risk to topological integrity that smoothing entails, I would forbid it in any application other than for cosmetic presentation of isolated objects.
