//     Function: CollisionTraverser::set_respect_prev_transform

//  Description: Sets the flag that indicates whether the
//               prev_transform stored on a node (as updated via
//               set_fluid_pos(), etc.) is respected to calculate
//               collisions.  If this is true, certain types of
//               collision tests will be enhanced by the information
//               about objects in motion.  If this is false, objects
//               are always considered to be static.  The default is
//               false.
