Thanks, I'm starting to understand. So Display Postscript was useful because it let you know that what you put on the screen as a programmer would be what's printed? And it allowed for cool graphics effects like custom strokes and fills. So that primarily matters for stuff you want to print. It wouldn't matter as much for assembling a UI. How does windows handle this stuff?

As a graphic designer/compositor/typesetter. Windows uses (used?) WMF and pixels for on-screen display which would then either be used for printout via some conversion process, or a parallel construction would be maintained for output and the need to keep that in synch would often result in slight differences in output --- maybe there were other approaches. One of the neat things in Display PostScript was one could use Interface Builder to add a print button to any window to get the underlying PS code.

In theory, you could also capture screenshots as high-quality vector graphics.

    Absolutely, since NeWS was largely the same concept, though with more intelligence on the PostScript side.
