Is there an actually convincing simple protocol for a 2D character buffer? (As opposed to a jumped-up typescript like the DEC terminals.) I’ve tried looking at the IBM tradition, and while it’s certainly different, I wouldn’t say it’s better on this particular point. (There is also the part where a VT100-style display is a bit more than just a character buffer—there’s rewrapping on resize, for example, which IIUC be on for some lines and off for others—but let’s assume we’re willing to postpone updating window contents until the resize is concluded so can afford to do that on the application/VT100-processor side. Even though that feels like 1995.)
