You all know the anchor point functionality for Bitmaps, and FINALLY it comes to Sprite, Shape .. AND all your own classes!
As far as I've tested it, there are no bugs, but hey, nobody's perfect. Please comment if you find something.
I've packed a demo project. Feel free to try.
Btw. I've added a class called Primitives, which makes creating Shapes absurdly easy. Head over to my website for documentation
And take a look at Gideros API
for anchor point usage.
