- Rename Collider::get_radius to bounding_radius
- Check origin difference in CapsulePrism with EPSILON * 10.0 instead of
magic 0.00001
- Add comments for closest_points, hardnened expression against NaNs
- Add comments to try_e2e_collision function, renamed to
resolve_e2e_collision, make it return whether collision was triggered.
- Remove Collider::Box (it is Cylinder, which is subset of CapsulePrism
with p0=p1=Vec2::zero())
