       gl_setdisplaystart - set the start of the screen are displayed


       #include <vgagl.h>

       vga gl_setdisplaystart(int x, int y);


       Set the physical display start address to the pixel at (x, y).

       Can  be  used  for  hardware  scrolling,  or  for  page  flipping (e.g.
       setdisplaystart(0, HEIGHT) displays from the second  page).  Make  sure
       the  scanline  width  (BYTEWIDTH)  in  bytes  of  the  current  context
       corresponds with the physical screen.

       Note also that the display start cannot be set to completely  arbitrary
       points, see vga_setdisplaystart(3).

       It is very likely that both are at least to some extent are due to Harm

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