No need to apologise - the reason why we (W3C) put out working drafts is
that we make mistakes, or write specs that don't include some community
or other because we don't know about them.

Again, feel free to post a comment requesting that the draft be made
clearer.

The only thing I see is that GIMP should be able to reproduce the
specified compositing effect accurately. Long term, I expect all
browsers to behave pretty much identically, to the extent this makes
sense in different hardware and operating environments. Certainly that's
the goal and the reason for the spec.
