Not to muddy the waters, but Dean has proposed a new Matrix class:

	http://lists.w3.org/Archives/Public/public-webapps/2011OctDec/0376.html

This attempts to solve the problem that both CSSMatrix and SVGMatrix are immutable and are therefore less efficient, since they always create new matrix objects. This new class attempts to be a functional superset of CSSMatrix and SVGMatrix (although the equivalent methods are named differently) in addition to being more efficient for matrix heavy clients like WebGL.

Perhaps it would be a good idea to focus on how this new class interacts with CSSOM, and consider CSSMatrix and SVGMatrix as legacy subsets of this class?
