Yeah, I wasn't planning on accessing any video card directly at the expense
of other cards.  Heck, if I wanted to do that I'd be working in DOS instead
of OS/2! :-)  I just thought that the Gpi routines would be a bit slow since
they have a variety of raster operation codes, and the support of those
undoubtably slows things down.  I need a simple, fast "give it two endpoints, 
a color, and let `er rip" line drawing routine.  I was wondering if there  
were an interface just below the Gpi level.

I've decided to try drawing with my own line drawing routine to an off-
screen buffer, and using DIVE to throw it to the screen.  I (finally)
got my DevCon CD, so today I'm studying how DIVE works.  

Thanks for the reply,
