 *  @param by y-coordinate of the fixed upper-left corner of the box to
 *         stretch or shrink.
 *  @param mw minimum width that the rectangle can be shrunk to.
 *  @param mh minimum height that the rectangle can be shrunk to.
 *  @param rec specify the "inside" box (??? TO BE CONFIRMED)
 *  @param rw pointer to a short integer which will be filled in with
 *         the ending width of the box when the mouse button is released. \n
 *         [option CHECK_NULLPTR] \a rw may be NULL
 *  @param rh pointer to a short integer which will be filled in with

 *  @param global_aes global AES array
 *
 *  @return 0 if an error occurred or non-zero otherwise.

 *
 *  @sa mt_graf_rubberbox()
 *
 *  This function should only be entered when the user has
 *  depressed the mouse button as it returns when the mouse
 *  button is released.
 *
 *  @note This call is similar to mt_graf_rubberbox(). It's usefull when resizing
 *        a window using the SIZER widget. The \a bx, \a by, \a mw and \a mh parameters define
 *        the whole window, and \a rect defines the work area of the window.
