Overview

Screen is a backend-neutral layout model.

It describes terminal geometry (rows/cols) and the logical regions that Fatty draws into (output/input/alert). Screen does not perform any IO and does not depend on curses.

Curses uses Screen to allocate resources (windows) and to understand where drawing should occur.
