Original Pull Request: https://github.com/microsoft/terminal/pull/15368

State: closed
Merged: Yes

This PR introduces four new escapes sequences: DECIC (Insert Column),
DECDC (Delete Column), DECBI (Back Index), and DECFI (Forward
Index), which allow for horizontal scrolling within a margin area.

References and Relevant Issues

This follows on from the horizontal margins PR #15084 to complete the
requirements for the horizontal scrolling extension.

Detailed Description of the Pull Request / Additional comments

The implementation is fairly straightforward, since they're all built on
top of the existing _ScrollRectHorizontally method.

Validation Steps Performed

Thanks to @al20878, these operations have been extensively tested on a
number of DEC terminals and I've manually confirmed our implementation
matches their behavior.

I've also added a unit tests that covers the basic execution of each of
the operations.

Closes #15109
