Why?
- Because we can.
- Because the TUI is just another GUI™
- Because it looks kinda nice, and provides useful context like 1 out of 100
times
Complies with "don't pay for what you don't use".
Some crashes for resizing were unfolded, add tests for those.
Initially we will use this for the popupmenu, floating windows will
follow soon
NB: writedelay + compositor is weird, we need more flexible
redraw introspection.
