+//     Function: Character::calc_tight_bounds
+//       Access: Public, Virtual
+//  Description: This is used to support
+//               NodePath::calc_tight_bounds().  It is not intended to
+//               be called directly, and it has nothing to do with the
+//               normal Panda bounding-volume computation.
+//
+//               If the node contains any geometry, this updates
+//               min_point and max_point to enclose its bounding box.
+//               found_any is to be set true if the node has any
+//               geometry at all, or left alone if it has none.  This
+//               method may be called over several nodes, so it may
+//               enter with min_point, max_point, and found_any
+//               already set.
+//
+//               This function is recursive, and the return value is
+//               the transform after it has been modified by this
+//               node's transform.
