// `_test_ccd` prevents tunneling by slowing down a high velocity body that is about to collide so
// that next frame it will be at an appropriate location to collide (i.e. slight overlap).
// WARNING: The way velocity is adjusted down to cause a collision means the momentum will be
// weaker than it should for a bounce!
// Process: Only proceed if body A's motion is high relative to its size.
// Cast forward along motion vector to see if A is going to enter/pass B's collider next frame, only proceed if it does.
// Adjust the velocity of A down so that it will just slightly intersect the collider instead of blowing right past it.
