View Ref-File7.5.8  Bindings for v_bez                                          TOS

 C:          void v_bez ( int16_t handle, int16_t count, int16_t 
             *xyarr, int8_t *bezarr, int16_t *extent, int16_t *totpts, 
             int16_t *totmoves );

 Binding:

             {
                ptsin[0..2n-1] = xyarr[0..2n-1];
                intin[0..(n+1)/2-1] = bezarr[0..n-1]
 
                contrl[0] = 6;
                contrl[1] = n;
                contrl[3] = (n+1)/2;
                contrl[5] = 13;

              ptsout     ptsout[0..3]          extent[0..3] 

             Note: The binding for this function has to swap the bytes 
             in intin because unfortunately this function is 
             compatible with PC-GEM. => bezarr[0] is the low byte of 
             intin[0], bezarr[1] is the high byte of intin[0]...
