I'm getting a strange crash on iOS, MAC & HTML5, but works fine in windows.

I think I've tracked it down to the SetSpriteShape function. I get the following error for the HTML5 version, but Mac & iOS just crashed out.

I noticed that as I changed the animations for an individual sprite that the collision shape was not being reset properly, so I had to use SetSpriteShape again to set the correct collision shape.

This could happen if the polygon shape has zero area, which would depend on the image it is trying to create a collision shape for. The image has to have some non-transparent pixels for the polygon shape to work.

I just tried removing a tween that was scaling the sprite to zero and the crash stopped. I guess this is weird behaviour.
