Interesting.  Does anyone know any of any graphics libraries or ones that 
will have it in the future which support the hardware acceleration 
included in many video cards, in other words, DirectVideo style?  That 
would be pretty neat... hardware accelerated bitblits and other stuff, 
all accessible from a library... for DJGPP ONLY!
