Yes. I sort of skipped over 3.8. Thanks for the feed
back. When I get back from holiday travel I go back to
3.7 full and resave the projects.

Yeah. I left some interesting stuff out of the
changeset that does the math. It was much more than
needed here but very interesting in developing

This was a backwards compatibility issue. I wanted to
isolate at first all the changes into curvier and
leave the users of polygon with what they expected.
Inorder not to break anything inadvertantly. With the
acceptance of Curvier Curves
I intend move as much as possible into polygonMorph.
Ive started to do that but did not have time complete
it before this round of publication and sharing.
My focus right now is on debugging How to get
published in the squeak stream.

Hmmm. How do you do Etoy properties? I didn't attempt
to learn Etoy stuff. Just focused on something worth
doing that was simple/interesting to learn.

I think there might still be a problem with old star
still showing handles.
I use the first vertex as the point they use the
second. I check for this and the first time I adjust
the star correct for it. The old stars old handles
will jump once. Then everything should settle down.
Old stars without handles get corrected before
anything noticable happen. This was a small enough
hiccup I didnt put effort to correcting it.
(Hopefully everyone will be using the newer stars in
the future.) Does this explain what your seeing or are
you refering to something else?

Tweek the "above" parameter in the addStarHandle
stuff. They are a little hard to hit. I only had
myself for user testing.

Okay, thanks for proofing.

Thanks Ned, for the time and the interest.

Thanks Ill look into it.
