Inspired by this article on gamedev.net
This scene is made of 3 lights and 9 polygons. Hit the switch to toggle softshadow on or off. It's not optimized in any way. Gotta get it to work properly first.
I had some trouble with directors copypixel function with quads. It was solved with [#useFastQuads:true], some accuracy with the shadow was sacrificed.
I haven't taken care of partial softshadow yet, when the center of the light can't see the line but the edge of the light can. You'll see that when an shadow "jumps" in place moving the light around a corner.
