## Detailed Description of the Pull Request / Additional comments
Feedback for CursorWrap shows that users want the ability to constrain
wrapping for horizontal only, vertical only, or both (default behavior).
This PR adds a new dropdown to CursorWrap settings to enable a user to
select the appropriate wrapping model.

## Validation Steps Performed
Local build and running on Surface Laptop 7 Pro - will also validate on
a multi-monitor setup.
