	As I have recently swapped from a Borland Compiler, I am only just getting
used to the fact that DJGPP does not have any graphic drivers to speak of.
Although I now have polygon fills and lines running as part of my program,
they are incredibly slow. I am not looking to use someone else's graphics
libraries (e.g. that Allegro thing, I believe), I am just looking for a few
simple pointers to producing fast fills and line-drawing routines, which
place the results into a frame buffer I have set up named 'doublebuffer',
which is malloc'd at 64000, for the VGA card, mode 13h. Please note that I
am not that knowledgeable at assembly, as I use a variety of platforms to
program on, and all use different families of processors.
	Thanks in advance,

		-Thomas
