Module backend 

Pluggable rendering backends. Pluggable rendering backends.

The Output, Input, and Cursor traits (plus the Backend bundle that ties them together) and the dependency-free Headless test backend live here. Platform backends (crossterm, software/winit) are separate crates (retroglyph-crossterm, retroglyph-software) that depend on this one and implement these traits.
