   Yeah! And much more!  The ggilib is the user-interface. Someone should test 
   if it will work with all svgalib binaries. After that we can remove svgalib
   and then we have much less problems on porting! I think zgv is a good 
   starting point -- not for the boot-floppies but in generell. 

I'm not putting ggilib on my bootdisks, I'm writing a very tiny
graphics library of my own.  Current, or perhaps slightly old (the
machine that has the latest version isn't on now), header shown below:
