               rectangle.

 Opcode:       73

 Syntax:       int16_t graf_growbox ( int16_t gr_gstx, int16_t 
               gr_gsty, int16_t gr_gstwidth, int16_t gr_gstheight, 
               int16_t gr_gfinx, int16_t gr_gfiny, int16_t 
               gr_gfinwidth, int16_t gr_gfinheight );

 Description:  The call graf_growbox draws an animated rectangular 
               outline box growing from one set of coordinates to 
               another (complement to graf_shrinkbox). The following 
               apply:

                Parameter      Meaning

                gr_gstx        X-coordinate,
                gr_gsty        Y-coordinate,
                gr_gstwidth    Width, and
                gr_gstheight   Height of the outline box at start
                gr_gfinx       X-coordinate,
                gr_gfiny       Y-coordinate,
                gr_gfinwidth   Width, and
                gr_gfinheight  Height of the outline box at end

               Note: As of PC-GEM Version 2.0, this call is ignored. 
               The reason given for this is the legal dispute between 
               Apple and Digital Research.
