Found a graphics rendering library

After spending some time trying to look for ways to draw lines and ellipses,  I realized that this is a deep subject - even without the anti-aliasing complexity. So I decided to use an existing library.

Very quickly, I hit upon libgd - http://www.libgd.org

Now, I think I have all that is needed to build my drawing utility...then do the documentation of Minix and then proceed with Minix....
