Weren't there ranges of values as well?

I think so. The other problem is that (cc @anthrotype) this repository is being absorbed into fonttools. So I'm not sure it would be useful to add new things to...

Ok then. * Considering the axis element is already a bag of all sorts with `map` and `labelname` elements, maybe we can do without the `valuenames` wrapper. * These names...

So this is a proposal `` element for instance. Do we need one for the top level as well? And would that be a way out for STAT data?

Could you give an example of these custom parameters?

Right, so I thought if there are things in there that have proper names and functions it might be useful to call those out.

Yeah, I was thinking. - Do variable fonts allow multiple designspace points to map to a single userspace point? - If we can calculate a single designspace point for any...

- Currently Bender only transforms designspace to userspace. - A cheap solution for going in the opposite direction would be to just build another mutator with the swapped values. -...

For mutatorMath I've added a branch for some work on bender user spaces. https://github.com/LettError/MutatorMath/commit/499f9a05c04aff417702c6c798e39962fbcead5e This lets the bender map in the **userspace** -> **designspace** direction. This can be used in...

Should axis extrema, master locations, instance locations, rule thresholds all be specifiable as mapped in userspace? To be sure: - **user space** is the value available to the user, the...
