Interestingly the entire NextStep UI was built on a graphics format called Display Postscript when Apple acquired it as the foundation of OS X https://en.m.wik

an idea that NeXT copied from Sun Microsystems NeWS

  Is there a citation for that? I thought Adobe built this with NeXT separately but clearly Adobe would know of NeWS too.

    Here's a comment from 2016 that quotes technical discussions from 1988. It is clear that the Display Postscript implementers had detailed knowledge of NeWS. "In a few cases they picked the same names and operator spec as us, but in general they didn't try to be compatible. A few incompatibilities seem gratuitious to me." https://news.ycombinator.com/item?id=11520455 https://news.ycombinator.com/item?id=11520455

The other thing that Apple did while developing OSX was to replace Display PostScript with an in-house implementation of Adobe's open PDF specification. https://en.wikipedia.org/wiki/Quartz_2D https://en.wikipedia.org/wiki/Quartz_2D

  Beacuse Apple and Adobe could not agree on licensing costs.

    I think it had just as much to do with adding a better compositing layer. That was when suddenly the GUI had a third dimension.
