Issue description

When firing a raycast from inside a static body or area, it can not detect collision with the corresponding collision shape. It seems like there is a back-faces culling going on.

Steps to reproduce

Try catching a collsion using a raycast from inside a collision shape. It seems it is culling back faces of the collision shape. Outer raycasts can of course detect collisions with no problem. I cannot see a simple way to reproduce the desired effect with the current behavior.
