If the library you're porting is the S-wafers (as I suspect)
you don't need  graphics.h, etc.  The C graphics code we have in
there was only for performance (we were invoking the device driver's
polygon function directly in C); however, newer hardware and software
may not require this hack.  I suggest you use the R polygon()
function directly.
