This will look for lib keys in `doc.libKeysForProcessing` and try to process them. italicSlantOffset is preloaded to the list. The test data has an extra key and values added and...

Hm. It doesn't have a logger when it expects one. In your code, could it be the `debug` attribute is set to True some point after initialisation? A logger is...

Alternatively, `ds.debug` could get a setter method which then can start the logger if there isn't one.

As a workaround, before this gets to a RF near you, if this is a scripted context, you can call `ds.startLog()` before calling `ds.makeOneGlyph()`

Alternative workaround, DSE could start the logger on a UFOProcessor that gets handed to a script.

This script works with the new release.

Thanks for the test!

This value relates to glyph geometry. Therefore it would be eligible for interpolation.
