RT 98539 - flatness() method not working?

PDF::API2 v2.022   Perl 5.16.3  Windows 7   severity: Important

In Content.pm, the flatness() method does not appear to have any effect in test cases I've written. Can anyone confirm that it is in fact working, and provide a test case or two that clearly demonstrates it? The code itself does appear to produce the right PDF command: $flatness i , and so passes the "t" test. However, there is no visible effect on either an arc() or a curve() (Bezier cubic). Everything looks perfectly smooth. I'm looking for test cases that demonstrate this for future documentation of the product. Thank you!

Can anyone provide some test cases illustrating various values of flatness? As I said before, all my tests produced perfectly smooth
curves, so maybe I'm using it incorrectly. Thanks.

The PDF code produced appears to be correct, but all curves are quite smooth, even cranking up the flatness value to 50 or 100! I would really appreciate it if someone could post test cases or examples demonstrating what various flatness values are supposed to do. Even better, use the flatness() method itself. From that, I can see if the PDF output is indeed correct, and enhance the documentation or fix the code, whichever is needed.
