What’s “a sensible value” if italic correction is done on node
level? There’s tfmdata.properties.autoitalicamount and
tfmdata.parameters.slantfactor if you need the information .
We could certainly set further fontdimensions in addition to the
one we do already (no. 8), but if we spend time on that part then
why not supply the entire list in one go? Someone knowledgeable
about font parameters and how they translate to the original
values would have to supply the code, though, especially when it
comes to the more delicate parts described in appendix G.
