       gl_setscreenoffset - set a memory offset for copyscreen


       #include <vgagl.h>

       void gl_setscreenoffset(int o);


       Set  the  offset  in  pixels  into  video  memory for copyscreen(3) and
       copyboxtocontext(3), copyboxfromcontext(3) and thus  allows  for  page-
       flipping.  Must  be  a  multiple  of the scanline width in bytes. It is
       reset to zero after the completion of copyscreen(3).

       Occasionally  this  might be wrong. I hereby asked to be excused by the
