canvas v5 has a currentTransform that is an SVGMatrix, as well as the ability to reset it, and perform some matrix functions.

I think new layout test can pass to chromium port after applying "patch v.2".

I'll very appreciate if Dean or Simon take a look at this bug.

This patch does most probably not apply anymore and is not the right way to go. We should use a more SVG unrelated approach like with the Matrix proposal in bug 110001.

It seems this got redesigned at some point in the specification.
