For WindTerm: No color scheme used in windterm. Color scheme will result in approximately 2% loss and more memory usage.

For Alacritty: Can not find how to set the scrollback lines limit, so every test use its default setting and no memory usage measured.
For Alacritty: Only supports up to 100,000 scrollback lines, so every test use "history: 100000" setting and no memory usage measured.

For Windows Terminal: Only supports up to 65,535 scrollback lines, so every test use "historySize: 65535" setting and no memory usage measured.
