I thought that libSDL (which is what's underneath) is limited to one window.
The documentation says that's not so. That said, I found libSDL to be quite
limited when I tried to use it to display emulated plotter output. The problem
there was that it's much bigger (pixel wise) than the screen and handling that
was problematic.
I've used wxWidgets a lot for portable windowing applications. I wonder if it
might make an attractive alternate base for sim_video.
