Depends on the browsers.  "pixelated" has a specific required
implemenation, but "crisp-edges" can be smarter/prettier, using
pixel-art scaling algorithms.

I agree on the need for a figure - I've got a good one that I use in
talks that I really need to copy into the spec.

I've received feedback both ways.  I can log this as an issue and get
some more feedback.

It varies per feature.  This particular feature is intended to be
stable, though until public implementations appear it's still possible
to change.
