Performance:
* for scrollback, investigate using segmented list for sufficiently large
scrollback scenarios.
* reflow: text reflow is really poorly implemented right now specifically
for shrinking columns. Look into this. This may require changing the
screen data structure.
* Loading fonts on startups should probably happen in multiple threads
* Windowing event loop should not check `shouldClose` on every window
and should use should close callbacks instead.
* Window shutdown should be done in threads but GLFW window close cannot
be done in multiple threads making this a bit tricky.
* `deleteLines` is very, very slow which makes scroll region benchmarks terrible
Correctness:
* `exit` in the shell should close the window
* test wrap against wraptest: https://github.com/mattiase/wraptest
- automate this in some way
* Charsets: UTF-8 vs. ASCII mode
- we only support UTF-8 input right now
- need fallback glyphs if they're not supported
- can effect a crash using `vttest` menu `3 10` since it tries to parse
ASCII as UTF-8.
Improvements:
* scrollback: configurable
* selection on top/bottom should scroll up/down (while extending selection)
* shift-click and drag to continue selection
Mac:
* Set menubar
* Preferences window
Major Features:
* Reloadable configuration
