dCylinderEnableCircleCollideTest(bool) enable/disable
the cylinder 'circles' colliding.
Use case : a robot owns 2 wheels that are inside the
robot volume : in this case, circles will never
collide with anything. Disabling circles tests should
decrease CPU charge in multirobots simulations.
It is possible to do that with the capsule:
dCapsuleEnableSpheresCollideTest(bool)
LR
This is better addressed with collision masks.
