 Syntax:       int16_t graf_shrinkbox ( int16_t gr_sfinx, int16_t 
               gr_sfiny, int16_t gr_sfinwidth, int16_t gr_sfinheight, 
               int16_t gr_sstx, int16_t gr_ssty, int16_t gr_sstwidth, 
               int16_t gr_sstheight );

 Description:  The call graf_shrinkbox draws an animated rectangular
