"liveness" of SVGMatrix

Four years ago there was a thread about whether an SVGMatrix passed to
SVGTransform::setMatrix is "live", i.e. whether subsequent changes to that
matrix object affect the transform. The thread started here.
http://lists.w3.org/Archives/Public/www-svg/2004Jun/0016.html

There was followup discussion in this Bugzilla bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=249263
where people explained some use cases for having the matrix be "live".

As far as I can tell the 1.1 spec has still not been clarified to indicate
whether the matrix is live or not. Please come to a decision and issue a
spec update to indicate whether it's live or not.

Thanks,
Rob
