But Mike, the mechanism will almost certainly be the one above, which is
actually quite general.

This bug is not strictly, or even not basically, about the UI, but the 
capability. If that's in place, there would be the discussion of how to expose
it in a way which doesn't clutter the UI. Perhaps some features will have more
exposure, and others less. At any rate, initially nothing will be exposed, and
exposure may require "targeted" issues.

(not part of the reply)

but I should mention a few points of difficulty: 

* When inheriting from multiple styles, it may not be clear which is the parent
to which to relate additions, multiplications, flips etc. Solution: If all of
the parents which have the relevant feature set (directly or by inheritance)
agree, then the agreed value is used; otherwise, setting a relative value is an
error.

* There is setting relative to the parent style, and setting relative to a
style in another family. Specifically, CS settings relative to PS settings, or
to the default CS of a PS. How should that be treated? As a "weak parent" in
addition the "proper parent" of the CS?

* Categorical settings (i.e. several discrete options which aren't necessarily
ordered) don't typically admit some universal relative settings. And yet - for
some of these, relative settings may be interesting. Example: A flipped
direction
