I checked MSCSSMatrix and WebKitCSSMatrix. Both have a method called setMatrixValue which takes a DOMString as argument. This DOMString takes a <transform-list> in the CSS Transforms notation. Percentage length values and relative length values throw a SyntaxError exception for both engines. It is at least another possibility. I am not sure if UAs can access font data without a document even though it should be possible.
