Casts a ray through the scene and returns all hits. Note that order is not guaranteed.

Notes: Raycasts will not detect colliders for which the raycast origin is inside the collider.
If you move colliders from scripting or by animation, there needs to be at
least one FixedUpdate executed so that the physics library can update it's data structures, before a Raycast will hit the collider at it's new position.
