Yeah, I vaguely looked at nuklear (at a glance, for a simple "what could be done" PoV), and, AFAICT, we'd "just" need basic primitive drawing capabilities for the software rasterizer (i.e., lines, circles, polygons & co. Currently, FBInk makes do with flat filled rectangles only). Didn't look at the font handling at all, though

I don't have any urgent need for a GUI anywhere myself, but that was interesting stuff to look at
