I have managed to get graphics to work in DJGPP by doing all the work
on an off screen buffer, and the copying the whole thing to VGA memory
in one go. So I only have to set the selector once, and the use a rep
movsb command. I have also made this work with SVGA graphics, VESA 1.2
and VESA 2 linear frame buffers. If I were to use near pointers would
it make it any faster?
