/** \todo Terrain uses its own transform that is independent of the placeable. It is not nice to support, since rest of RigidBody assumes
the transform is in the placeable. Right now, we only support position & scaling. Here, we also counteract Bullet's nasty habit to center
the heightfield on its own. Also, Bullet's collisionshapes generally do not support arbitrary transforms, so we must construct a "compound shape"
and add the heightfield as its child, to be able to specify the transform.
