The canvas draft spec used to have a currentTransform attribute on 2D canvas context objects, which was implemented by Chrome (behind a runtime flag). We also ship our own similar (but non-standard) mozGetTransform and mozSetTransform methods.
The draft spec has since changed to add a getTransform method returning a DOMMatrix, and a setTransform method that accepts a new DOMMatrixInit dictionary. It seems that the Chrome team intends to support these new methods instead of currentTransform, so I would like to implement them as well, and help push the spec forward.
