After fiddling around a bit more, I think I've discovered what's actually
happening.

I think in the first case, ncurses output, which is consistently being sent to
stdout in both cases, is indeed being written to cube.png (which is obiously not
what I want); and then at the end of rendering, the in-core png image is then
written to cube.png overwriting the previously written ncurses content of the
file making it disappear into the magician's hat.

Thanks to everyone for taking the time to respond.

Matt
