Hi David, If I can help (dev / test / build / patch), I would love doing it on this RFE... on my spare time as usual (best effort).
However I have no idea how text metrics are implemented in JavaFX. Could anyone give us directions or draft ideas to do the job ourselves ? Should we start a github repository to fix that issue with all interested people ?
