Difference between full screen, focus mode and quake window

[zadjii-msft]

From @htcfreek in microsoft/terminal#13799

What is the difference and correct usage of the follwoing window types:

• full screen window
• focus window
• quake mode window

For me the full screen window looks the same as an fokus window except that a fokus window is not on the full screen. Both have not tab row, title bar and window border. Here is a screenshot of wt after enabling the "focus mode":

If I choose "Show/hide quake window" in the command palette on a normal window, nothing happens. Same on a quake window.

maintainer note: maybe we just need a top-level "focus mode" page, or a top-level "features" with something like focus mode (& cmdpal, search, ) under it
