/**  changes the display state of an object.
 *
 *  @param tree  specifies the object tree of the object to modify.
 *  @param object specifies the object to modify.
 *  @param res is reserved and should be 0.
 *  @param cx x-position of the the clipping rectangle if the
 *         object is to be redrawn.
 *  @param cy y-position of the the clipping rectangle if the
 *         object is to be redrawn.
 *  @param cw width of the the clipping rectangle if the
 *         object is to be redrawn.
 *  @param ch height of the the clipping rectangle if the
 *         object is to be redrawn.
 *  @param new_state specifies the new state of the object (same as
 *         ob_state).
 *  @param redraw may be one of the following value:
 *         - #NO_DRAW (0) : the object is not redrawn
 *         - #REDRAW (1) : the object is redrawn.
 *  @param global_aes global AES array
 *
 *  @return 0 if an error occurred and non-zero otherwise.
 *
 *  @since All AES versions.
 *
 *  @sa mt_objc_draw()
 *
 *  In general, if not redrawing the object, it is usually
 *  quicker to manipulate the object tree directly.
