 the bullet does a continuous check after all non-bullet bodies have moved. You could get unlucky and have
 the bullet body end a time step very close to a non-bullet body and the non-bullet body then moves over
 the bullet body. In continuous collision, initial overlap is ignored to avoid freezing bodies in place.
 I do not recommend using them for game projectiles if precise collision timing is needed. Instead consider
 using a ray or shape cast. You can use a marching ray or shape cast for projectile that moves over time.
 If you want a fast moving projectile to collide with a fast moving target, you need to consider the relative
 movement in your ray or shape cast. This is out of the scope of Box3D.
