To reviewer:

I should have converted to float instead of int? Current callers either use
unsigned or unsigned short. The whole convert to template type T without range
checks in this method feels bad in the first place.

Ints is right for borders. Good catch.

     if (valueID == CSSValueInvalid) {
         float zoom = state.style()->effectiveZoom();
         // Any original result that was >= 1 should not be allowed to fall below 1.
