for 100% BC you can require the renamed classes manually (but if some other updated code required them before use is enough)

@georgehristov Is there any naming inconsistency in this PR/repo or other repo to address? Can you check quickly and/or do you have something in mind to change from past? Would be good if we can close these naming issues at now.

@ibelar what is the purpose of jUniv, is it used somewhere?

• not used in ui
• what is the univ.min.js file, something from past?

it is only a stub for autohinting, can/should we refactor code to use it or should we drop it?
