[Etoys] [FIX]Handle sizes
Hi Yoshiki,
Stars are drawn starting at an inner corner and the handle is placed on the first outer corner.
When stars are redrawn the first inner corner restarts from the corner at the smallest angle. So if you twist a star through say a half turn then pick it up and put it down. It gets redrawn and the outer handles location changes points to be back near the left. At least thats what I remember. Actual details may be slightly different. The jist should be correct.
When I did my iteration to unleash stars I considered this a bug and fixed it. I had the star start on an outer handle and made the redrawing always start at that point. This stablized the handles quite nicely.

I will point out that the star code can be adopted for the fixes and you can throttle back the menu and handle abilities until you emulate what is there now. You still would get the fixes.

For unrelated note, I discovered that if you show
the handles for a
Star, resize it by the "outside" handle and then
click on somewhere in
the Star, the position of outside handle changes. Do
you know why
that is?

Hi, Jerome,
Your StarMorph change is isolated enough and StarMorph is not used anywhere (unlike Polygons), so I think I would like to include your change (with some modifications of default values). Thank you!
