Convex Hull of One Point

[randallwhitman]

Expected: non-empty degenerate polygon.
Actual: empty geometry.
Is there a different way I should be calling the convex-hull operator?
Relates SF4H-181.

 private static class OnePointCursor extends GeometryCursor {
 private boolean flag = true;
 OnePointCursor() {}
 public Geometry next() {
 if (flag) {
 flag = false;
 return new Point(1.2, 3.4);
 } else
 return null;
 }
 public int getGeometryID() {
 throw new UnsupportedOperationException();
 }
 }

 @Test
 public static void testOnePoint() {
 GeometryCursor geomCursor = new OnePointCursor();
 GeometryCursor convexResult = OperatorConvexHull.local().execute(geomCursor, true, null);
 Geometry result = convexResult.next();
 System.err.println(result); // {"rings":[]}
 assertFalse(result.isEmpty()); // junit.framework.AssertionFailedError
 }

works for me

A point polygon, or polygon which is degenerate to a line is not valid for many operations, so I am not sure what would you be able to use it for.
The merge=false version of the operator returns point if convex hull is a point, or a line if convex hull is a line.
The merging version should probably do the same.

Btw, I tested with Geometry-2.2.4 ; I believe Jordan tested with something else.
