On Mac OS at least, you are flat-out wrong as of 8.5 or so (when I stopped using Mac OS).

I am pretty sure this has always worked since the introduction of Desktop Printers in Mac OS 8. But I have verified that it DOES work with Mac OS 9.x.

Yeah, maybe what I wanted was more "Postscript is a g[l]orified

Same thing. SGML is not a page description language, it's a textual markup language - same things apply.

I'm not suggesting that
hand-writing a document in PS is any kind of fun. :^>)

No argument there - though there are folks who would disagree ;).

You want screen draws/blits to be as fast as possible (hence the need for hardware acceleration of same). If you have to parse/interpret a programming language to draw on the screen (which is what you did indeed do with DPS!), then it will NOT be fast!

And giving a userland process access to your video card's DMA
(and, by way of that, all memory), which anyone running XFree86 is
doing, is better somehow?

Different issues...
