I have an existing DJGPP app that displays images, plots, etc. by doing
direct writes to video memory.  The graphics in this app won't work
under NT or 2000, for well-known reasons.  I would like to get this
program to work under NT/2000 by redirecting the graphics writing to a
malloc'ed region (which I can do easily), then calling a Windows
function to copy the image to a window.  Thus, I'd have two windows
open; a text window just as before, and a graphics window.

Is this feasible to do?  I have looked at 3.6 of the FAQ, but am still
uncertain how to proceed.  I don't want a Windows-hosted compiler (the
DJGPP tools suit me just fine :-), nor do I need to create full-blown
Windows apps.
