// NOTE: This test is quite complicated so here is an explanation.
// First, we associate the following bit masks:
// - DYNAMIC = 0001
// - STATIC = 0010
// - FIXED = 0010
// - KINEMATIC = 1100
// These are equal to the bits indexed by `RigidBodyType as u32`.
// The bit masks defined by ActiveCollisionTypes are defined is such a way
// that the first part of the variant name (e.g. DYNAMIC_*) indicates which
// groups of four bits should be considered:
// - DYNAMIC_* = the first group of four bits.
// - STATIC_* = the second group of four bits.
// - FIXED_* = the second group of four bits.
// - KINEMATIC_* = the third and fourth groups of four bits.
// The second part of the variant name (e.g. *_DYNAMIC) indicates the value
// of the aforementioned groups of four bits.
// For example, DYNAMIC_STATIC means that the first group of four bits (because
// of DYNAMIC_*) must have the value 0010 (because of *_STATIC). That gives
// us 0b0000_0000_0000_0010 for the DYNAMIC_STATIC_VARIANT.
// For example, DYNAMIC_FIXED means that the first group of four bits (because
// of DYNAMIC_*) must have the value 0010 (because of *_FIXED). That gives
// us 0b0000_0000_0000_0010 for the DYNAMIC_FIXED_VARIANT.
//
// The KINEMATIC_* is special because it occupies two groups of four bits. This is
// because it combines both KinematicPositionBased and KinematicVelocityBased.
