You're right. I looked closely at the text in CSS 2.1 and 2.2 and length definitions are the same. CSS 2.1 contains a warning that several sections have been updated. Yet this particular one seems to have remained the same.

Yet the fix is still required. Swing handles High DPI by scaling all UI therefore all length units factors should not depend on the screen resolution or print resolution, the changes in resolution are automatically handled by 2d transform.

However, changing the link to the CSS specification is optional. Shall we update it to the most recent one?
