Are those classes in their current implementations thread-safe ? Could a Web Worker easily do matrix calculations with them ? I would guess a basic physics engine in a worker would be a nice use case.

And what about making something that is generic enough for both SVG and CSS, or even full blown algebra ? And then specify bindings of implicit conversions from those DOM classes into a basic ES matrix (if you would like to call it that) ?
