This would indeed be my suggestion. I think there is more than one 
alternative that could make some sense, but the above is simple, very 
close to the original (it just adds the *aR at the end), and makes the 
output more useful, in my opinion.

BTW, when you're going to experiment, also try preserving the alpha 
channel. (And I think Inkscape still implements the above, so you don't 
necessarily have to code anything yourself to try it out.)
