* Applying Nlin's NINJA Joint patch. v2. Mantis# 2874
* Thanks nlin! * To try it out, set ninja joints active in the ODEPhysicsSettings and use the example at: * http://forge.opensimulator.org/gf/download/frsrelease/142/304/demo-playground.tgz. * Don't forget to change the .tgz to .oar and load it with load-oar.
