               for a metafile.

 Opcode:       5 (Escape 98)

 Syntax:       void v_meta_extents ( int16_t handle, int16_t min_x, 
               int16_t min_y, int16_t max_x, int16_t max_y );

 Description:  The call v_meta_extents updates the size information in 
               the header of a metafile. The following apply:

                Parameter  Meaning

                handle     Workstation identifier
                min_x      Minimum X-value, and
                min_y      Minimum Y-value of the smallest bounding 
                           box (the top left corner)
                max_x      Maximum X-value, and
                max_y      Maximum Y-value of the smallest bounding 
                           box (the bottom left corner)

               Notes: The size information can be used to obtain 
               quickly the minimum or maximum dimensions of all the 
               primitives stored in the metafile.

               The parameters sent to this call should be specified in 
               whatever coordinate system the metafile is using at the 
               time.
