Implement CSS text decoration properties text-decoration-thickness and text-underline-offset. Add support for the new from-font keyword for text-underline-position. When from-font keywords are used, support variable font MVAR underline scaling, (tags `unds` and `undo` in the MVAR table overriding underlinePosition and underlineThickness in the OpenType `post` table.

Motivation

With the introduction of the text-decoration-skip-ink interest for additional underline styling increased to improve situations where the underline as placed by the UA is too close to the baseline and ink-skipping triggers too early. High interest on the chrome bug #785230 (25 ⭐️) and shipped in Firefox and Safari.
