* Re-enable the AbsolutePosition = AbsolutePosition in the LSL_Api in the SetRot method if the object is not active physical. This is important for scripted rotating doors. without AbsolutePosition = AbsolutePosition, the door won't rotate. It's also important that we do not use AbsolutePosition = AbsolutePosition if the object is active physical because that would cause a complete rebuild of the object which would break vehicles. This is the best of both worlds right now. Doors as child prim should work again so long as you don't check the Physical box.
