//     Function: ModelNode::set_preserve_transform
//       Access: Public
//  Description: Sets the preserve_transform flag.  This restricts the
//               ability of a flatten operation to affect the
//               transform stored on this node.  If the flag is:
//
//               PT_none - the transform may be adjusted at will.
//
//               PT_local - the local (and net) transform should not
//               be changed in any way.  If necessary, an extra
//               transform will be left on the node above to guarantee
//               this.  This is the strongest restriction.
//
//               PT_net - preserve the net transform from the
//               root, but it's acceptable to modify the local
//               transform stored on this particular node if
//               necessary, so long as the net transform is not
//               changed.  This eliminates the need to drop an extra
//               transform on the node above.
