We haven't bound any SDL routines for that yet. It would be great if you
could look at the SDL documentation for drawing routines and provide a small
patch to iulib/utils/dgraphics.{cc,h}

That's because you're drawing a one pixel wide line, and you're probably
scaling the image down a lot during display; the line just disappears. If
you make it several pixels wide, you will be able to see it.
