- mintty:
- detection for iTerm format: mintty/mintty#881
- iTerm2:
- support: name, width, height, preserveAspectRatio options
- perhaps query tmux directly: TMUX=/tmp/tmux-1000/default,3218,4
- improve terminal identification 19:VT340 ESC[>0c = 19;344:0c https://invisible-island.net/xterm/ctlseqs/ctlseqs-contents.html
