- contact sleeping
- object link constraints
- optimizations
- convex hulls
- in some proximity queries we set distance == 0.0 and half_axis to zero if nearest_a
and nearest_b are "approx_eq"; should we instead calculate the distance and half-axis?
we will till compute the normal manually as if in contact if "approx_eq"; this is
because of rounding errors/floating point accuracy, the nearest points may not be
perpendicular to the contact surface
