 Opcode:       42

 Syntax:       int16_t objc_draw ( OBJECT *ob_drtree, int16_t 
               ob_drstart, int16_t ob_drdepth, int16_t ob_drxclip, 
               int16_t ob_dryclip, int16_t ob_drwclip, int16_t 
               ob_drhclip );

 Description:  The call objc_draw renders an object tree (or parts of 
               objects) on the screen. The following apply:

                ob_drstart  Index of the first object to be drawn
                ob_drdepth  Number of object generations to be drawn 
                            (0 = only the first object), maximum of 8
                ob_drxclip  X-coordinate, and
                ob_dryclip  Y-coordinate of top left corner,
                ob_drwclip  Width, and
                ob_drhclip  Height of the bounding rectangle

               Note: With the parameters one can specify a rectangle 
               to which drawing is to be restricted (clipping).
