Any questions?

So anyway, localToGlobal works fine. However globalToLocal is so broken it looks like some really bad use of sin() is going on. With it off, translating a point through a rotated object is fine. With it ON objects weave in and out of the screen and flicker every second frame. Which is exactly what happened when I originally wrote my own version of this function and got it completely wrong.

Fix it Macromedia.
