	I'm writing my first game in Djgpp and I'm trying to use Mode-X because of
the many advantages.  The only thing I don't like is the non-linear
addressing.  Whenever you plot a pixel you have to select the bit-plane
right?!  Okay I wrote a function to do that, but obviously it is somewhat
slower than say a 13h function.  My biggest problem is blitting.  How can I
blit in mode X without plotting one pixel at a time (as apposed to a say
memcpy command to blit whole lines).  Basically I want a fast and easy way
to copy a buffer containing an image to the video buffer in mode-X.  Maybe
that's not possible, maybe I should try VESA programming??  Any help would
be appreciated.
