[Feature]: Support for CSI 14

[microo8]

Feature description

CSI 14 is an escape code, that returns the screen size in pixels.

This feature would allow the running application to get the screen size, it is used mainly in sixel supporting apps, that need to scale the image before printing it out. This would be needed if this #2973 would me merged.

Another alternative is TIOCGWINSZ syscall.

I think I have a similar request, but I don't know anything about it at all. Here's from that discussion. https://github.com/hzeller/timg/issues/86

Can you elaborate on "not working"? It works in my testing:

[18:47:50:~]$ echo -e '\033[14t' ; cat

^[[4;1161;1056t

[18:48:22:~]$ echo -e '\033[16t' ; cat

^[[6;43;22t

[18:48:30:~]$

And also in a program I wrote that utilizes this escape sequence.
