Subject: 1969 - always hide screen before rendering

Also ensure we don't render unnecessarily.
This is really where I want a formal type-like system to help me.

All functions have paired calls to hide-screen and show-screen, except
for the one in main.

Only functions at the 'topmost' level are expected to hide/show.
