Setting for rulers on all 4 edges of the viewport

By default the ruler is viewed on the top and left border of the screen. I wish to have it on the bottom or right of the screen in addition incase I need to measure specific length from things designed from the bottom up. In my specific case I am drafting containers with varying width and volumes and only having the ruler at the top forces me to either drag the view cutting off most of the workspace, or play around with flips and rotations essentially designing upside down. Including a full perimeter ruler would address my issue.

The issue names no files, tests, or entry points; start by locating the viewport ruler implementation and its layout handling. Add optional rulers on the bottom and right while preserving the existing top and left rulers, then verify measurements can be taken from all four edges.
