Adobe's support for OpenType Variations does exactly the same –
welcome back, `blend' operator!

This is not correct.  It's only necessary to support `blend' and some
additional, minor stuff – no full PS interpreter needed.

Irrespective of OpenType Variations, I expect that there will soon be
fonts using Adobe's new `CFF2' font format (which is essentially a
subset of `CFF' plus support for `blend'), so luatex should probably
start with this.
