I'm a little worried about this one at first glance.

I suspect isIdentity is going to be used primarily for optimization.
But we want optimizations on the Web to be good -- we should care
about making it easy for authors to care about performance.  And I'm
worried that a flag-based isIdentity will not be useful for
optimization because it won't hit many of the cases that authors
care about, e.g., translating and un-translating, or scaling and
un-scaling.
