00003 *
00004 * A "vnode" object is a visual object that represents any client object.
00005 * It is used as a handle in the visual system. It contains a pointer
00006 * a pointer to the actual object, a tag that is a string identifying the
00007 * type of the object, a list of visual properties (vprops) that the
00008 * object has.
00009 *
00010 * When the object is freed, its dual vnode should also be deleted.
00011 * The visual_manager keeps track of all the vnodes, and makes sure that
00012 * there is only one vnode per client object.
