Description: tkinter.font.Font now copies the options of a named font (via "font configure") instead of the options resolved by "font actual", which would resolve a size specified in pixels (a negative size) to points. A font description is still resolved, as it cannot be parsed otherwise. Font.copy(), which has always been equivalent to constructing a Font from the original font, is updated to match and now preserves the size too. (cherry picked from commit 45010f4) (cherry picked from commit a9d4473) Co-authored-by: Serhiy Storchaka storchaka@gmail.com Co-authored-by: Claude Opus 4.8 noreply@anthropic.com Issue: gh-143990
