I don't think it can be.  At this point, I intend to modify the
backends a little, and add a new GDK/GTK+ backend.

What I'm not planning to attempt, yet, is replacing the way that

it is necessary to get some nicer-looking output for the GUI.

I was just planning to keep around the "struct tab_table" and
"struct som_entity" structures and render from them.  That ought
