This is meant to exactly mimic the terminal UI, just without
the restriction to ugly monospace fonts.
The Curses implementation has been reworked, and may have become
more computationally expensive. In general, though, the codebase
has been significantly cleaned up.
I was tired of using `mpv --no-video`, this is a bit better.
It's all rather quirky, but very little code is involved.
I've added a few related TODO entries.
