Or just use a PS reference book.

Well, if you yank out the PS from NeXTStep's DPS, you just have the display
portion, and that part won't be very different whether it's DPS, DDVI, DPDF,

Ghostscript is far from fast, and I've had problems with some of its
interpretation. DGS is very X centric (by design), and I imagine that
it was a lot easier to use pre-existing objects than to convert and
optimize someone else's code.
Yup, Apple did it from scratch, but it was easy. They already had nice PDF
objects to build upon, and there's no benefit to going with DGS over DPDF.
Plus, PDF is recognizeable to the masses, PS is not. When you need to
market your product, it's good to use things the market recognizes.
